	Title	Relaxation phenomena at the metal-to-insulator transition in La_0.8Sr_0.2MnO₃ single crystals			Type	A1 Journal article
	Year	2008	Publication	Solid state communications	Abbreviated Journal	Solid State Commun
	Volume	148	Issue	7/8	Pages	340-344
	Keywords	A1 Journal article; Electron microscopy for materials research (EMAT)
	Abstract	The time dependence of the resistance RAC of a La0.8Sr0.2MnO3 single crystal has been investigated in the vicinity of the metal-to-insulator transition temperature. We used local probe microscopy to show the existence, at room temperature, of coexisting clusters of micrometer size. Our analysis shows that relaxation effects can be described with a simple exponential contribution using a random resistor-network, based on phase separation between insulating and metallic domains. Our results clearly prove the existence of a percolation threshold over which no percolation path exists. Moreover, these results highlight the significant role of the remanent magnetization.

	Title	Magneto-ballistic transport through micro-structured junctions on a curved two-dimensional electron gas			Type	A1 Journal article
	Year	2009	Publication	Solid state communications	Abbreviated Journal	Solid State Commun
	Volume	149	Issue	19/20	Pages	778-780
	Keywords	A1 Journal article; Condensed Matter Theory (CMT)
	Abstract	We investigate theoretically the ballistic transport in a two-dimensional electron gas, which is rolled up as a tube and is micro-structured into a Hall bar. A uniform magnetic field applied to such a curved surface results in a non-uniform perpendicular magnetic field. The bend resistances become asymmetric with respect to the orientation of the magnetic field due to the varying magnetic field along the junction. The resistance asymmetry is strongly affected by corrugation due to the varying mobility along different crystallographic directions. We compare our results with a recent transport measurement.

	Title	Effects of nanocracks on the magnetic and electrical properties of La_0.8Sr_0.2MnO₃ single crystals			Type	A1 Journal article
	Year	2009	Publication	Solid state communications	Abbreviated Journal	Solid State Commun
	Volume	149	Issue	37/38	Pages	1543-1548
	Keywords	A1 Journal article; Electron microscopy for materials research (EMAT)
	Abstract	An investigation of the physical properties of La0.8Sr0.2MnO3 single crystals grown by the molten zone technique is realized close to the metal-to-insulator transition temperature (TMI). In this paper, we review the effect of the structural defects through magnetotransport and local magnetic microstructures. From electron microscopy observations, some nanocrack defects (i.e. defects at a nanometer scale) were found, essentially in the center part of the single crystals. At room temperature, magnetic force microscopy measurements have shown that the absence of defects allowed a magnetic ordering of the domains at the crystal edge, which is the best-crystallized region. In addition, the magnetization loops have permitted us to verify that the crystal was ferromagnetically weaker in the center. On analyzing the electrical resistivity data, we observed in the linear current regime a sensitive variation of the resistivity due to defects, by comparing the center and the edge of the material at TMI. Additionally, at strong current, non-linearity phenomena have been supposed to be related to local heating. Finally, we discuss the structural disorder effect on the relaxation of the ferromagnetic domains.

	Title	Landau levels and magnetopolaron effect in dilute GaAs:N			Type	A1 Journal article
	Year	2010	Publication	Solid state communications	Abbreviated Journal	Solid State Commun
	Volume	150	Issue	33/34	Pages	1575-1579
	Keywords	A1 Journal article; Condensed Matter Theory (CMT)
	Abstract	The magnetic-field dependence of the energy spectrum of GaAs doped with nitrogen impurities is investigated. Our theoretical model is based on the phenomenological band anticrossing model (BAC) which we extended in order to include the magnetic field and electronphonon interaction. Due to the highly localized nature of the nitrogen state, we find that the energy levels are very different from those of pure GaAs. The polaron correction results in a lower cyclotron resonance energy as compared to pure GaAs. The magneto-absorption spectrum exhibits series of asymmetric peaks close to the cyclotron energy ħωc.

	Title	Newtonian trajectories : a powerful tool for solving quantum dynamics			Type	A1 Journal article

	Keywords	A1 Journal article; Theory of quantum systems and complex systems; Condensed Matter Theory (CMT)
	Abstract	Since Ehrenfests theorem, the role and importance of classical paths in quantum dynamics have been examined by several means. Along this line, we show that the classical equations of motion provide a solution to quantum dynamics, if appropriately incorporated into the Wigner distribution function, exactly reformulated in a type of Boltzmann equation. Also the quantum-mechanical features of the canonical ensemble can be studied in this framework of Newtonian dynamics, if the initial distribution function is appropriately constructed from the statistical operator.

	Title	Annular dark field imaging in a TEM			Type	A1 Journal article
	Year	2004	Publication	Solid state communications	Abbreviated Journal	Solid State Commun
	Volume	130	Issue	10	Pages	675-680
	Keywords	A1 Journal article; Electron microscopy for materials research (EMAT)
	Abstract	Annular objective apertures are fabricated for a CM300 transmission electron microscope using a focused ion beam system. A central beam stop in the back focal plane of the objective lens of the microscope blocks all electrons scattered up to a semi-angle of approximately 20 mrad. In this manner, contributions to the image from Bragg scattering are largely reduced and the image contrast is sensitive to the atomic number Z. Experimentally, we find that single atom scattering cross sections measured with this technique are close to Rutherford scattering values. A comparison between this new method and STEM-HAADF shows that both techniques result in qualitatively similar images although the resolution of ADF-TEM is limited by contrast delocalization caused by the spherical aberration of the objective lens. This problem can be overcome by using an aberration corrected microscope.

	Title	X-ray and electron spectroscopy investigation of the coreshell nanowires of ZnO:Mn			Type	A1 Journal article
	Year	2011	Publication	Solid state communications	Abbreviated Journal	Solid State Commun
	Volume	151	Issue	19	Pages	1314-1317
	Keywords	A1 Journal article; Electron microscopy for materials research (EMAT)
	Abstract	ZnO/ZnO:Mn coreshell nanowires were studied by means of X-ray absorption spectroscopy of the Mn K- and L2,3-edges and electron energy loss spectroscopy of the O K-edge. The combination of conventional X-ray and nanofocused electron spectroscopies together with advanced theoretical analysis turned out to be fruitful for the clear identification of the Mn phase in the volume of the coreshell structures. Theoretical simulations of spectra, performed using the full-potential linear augmented plane wave approach, confirm that the shell of the nanowires, grown by the pulsed laser deposition method, is a real dilute magnetic semiconductor with Mn2+ atoms at the Zn sites, while the core is pure ZnO.

	Title	Structural transitions in a classical two-dimensional molecule system			Type	A1 Journal article
	Year	2002	Publication	Solid state communications	Abbreviated Journal	Solid State Commun
	Volume	122	Issue	12	Pages	665-669
	Keywords	A1 Journal article; Condensed Matter Theory (CMT)
	Abstract	The ground state of a classical two-dimensional (2D) system with a finite number of charge particles, trapped by two positive impurity charges localized at a distance (z(0)) from the. 2D plane and separated from each other by a distance chi(p) are obtained. The impurities are allowed to carry more than one positive charge. This classical system can form a 2D-like classical molecule that exhibits structural transitions and spontaneous symmetry breaking as function of the separation between the positive charges before it transforms into two 2D-like classical atoms. We also observe structural transitions as a function of the dielectric constant of the substrate which supports the charged particles, in addition to broken symmetry states and unbinding of particles.

	Title	Bi_0.75Sr_0.25FeO_3-\delta : revealing order/disorder phenomena by combining diffraction techniques			Type	A1 Journal article
	Year	2012	Publication	Solid state communications	Abbreviated Journal	Solid State Commun
	Volume	152	Issue	5	Pages	331-336
	Keywords	A1 Journal article; Electron microscopy for materials research (EMAT)
	Abstract	The local and long range structure of polycrystalline samples of Bi0.75Sr0.25FeO3-delta has been probed by neutron and synchrotron X-ray diffraction coupled with transmission electron microscopy. It is found that the long range structure on average can be described by the cubic space group Pm-3m (a(p) congruent to 3.951 angstrom). However, the refinements revealed large atomic displacements for the (Bi, Sr) cations and the oxygen atoms from their ideal positions. The electron microscopy study indicates the existence of local phenomena like local ordering of oxygen vacancies, which are segregated at the randomly spaced parallel (FeO2-delta) planes, or the existence of region of different symmetry, probably R3c. At room temperature, the compound exhibits G-type antiferromagnetism (T-N congruent to 650 K) with a magnetic moment of congruent to 3.7 mu(B). (C) 2012 Elsevier Ltd. All rights reserved.
