Title Formation of vortex shells in mesoscopic superconducting squares Type A1 Journal article
Year (down) 2009 Publication Superconductor science and technology Abbreviated Journal Supercond Sci Tech
Volume 22 Issue 3 Pages 034001,1-034001,8
Keywords A1 Journal article; Condensed Matter Theory (CMT)
Abstract We study vortex configurations in mesoscopic superconducting squares. Our theoretical approach is based on the analytical solution of the London equation using the Green's function method. The potential energy landscape found is then used in Langevin-type molecular-dynamics simulations to obtain stable vortex configurations. We show that the filling rules for vortices in squares with increasing applied magnetic field can be formulated, although in a different manner than in disks, in terms of the formation of vortex 'shells'. We discuss metastable states and the stability of the vortex configurations found with respect to variations of the material parameters and deformations of the shape of the sample.

Title Vortex states in mesoscopic superconducting squares: formation of vortex shells Type A1 Journal article
Year (down) 2008 Publication Physical review : B : condensed matter and materials physics Abbreviated Journal Phys Rev B
Volume 78 Issue 10 Pages 104517
Keywords A1 Journal article; Condensed Matter Theory (CMT)
Abstract We analyze theoretically and experimentally vortex configurations in mesoscopic superconducting squares. Our theoretical approach is based on the analytical solution of the London equation using Green's-function method. The potential-energy landscape found for each vortex configuration is then used in Langevin-type molecular-dynamics simulations to obtain stable vortex configurations. Metastable states and transitions between them and the ground state are analyzed. We present our results of the first direct visualization of vortex patterns in micrometer-sized Nb squares, using the Bitter decoration technique. We show that the filling rules for vortices in squares with increasing applied magnetic field can be formulated, although in a different manner than in disks, in terms of formation of vortex “shells”.

Title Multiple flux jumps and irreversible behavior of thin Al superconducting rings Type A1 Journal article
Year (down) 2003 Publication Physical review : B : condensed matter and materials physics Abbreviated Journal Phys Rev B
Volume 67 Issue 5 Pages 054506-6
Keywords A1 Journal article; Condensed Matter Theory (CMT)
Abstract An experimental and theoretical investigation was made of flux jumps and irreversible magnetization curves of mesoscopic Al superconducting rings. In the small magnetic-field region the change of vorticity with magnetic field can be larger than unity. This behavior is connected with the existence of several metastable states of different vorticities. The intentional introduction of a defect in the ring has a large effect on the size of the flux jumps. Calculations based on the time-dependent Ginzburg-Landau model allows us to explain the experimental results semiquantitatively.

Title Quenching of the Hall effect in localised high magnetic field regions Type A1 Journal article
Year (down) 2002 Publication Physica. E: Low-dimensional systems and nanostructures Abbreviated Journal Physica E
Volume 12 Issue 1/4 Pages 244-247
Keywords A1 Journal article; Condensed Matter Theory (CMT)
Abstract We report the suppression of the Hall effect in a mesoscopic Hall cross with a strong magnetic field only in the centre and vanishingly small outside, The local magnetic field is produced by placing Dy pillar on top of a structure with a high-mobility two-dimensional electron gas. The effect is found to be due to a sharp increase of the number of back-scattered and quasi-localised electron orbits. The possibility of localising electrons inside the magnetic inhomogeneity region is discussed. (C) 2002 Elsevier Science B.V. All rights reserved.

Title Scattering of ballistic electrons at a mesoscopic spot of strong magnetic field Type A1 Journal article
Year (down) 2002 Publication Physical review : B : condensed matter and materials physics Abbreviated Journal Phys Rev B
Volume 65 Issue 23 Pages 233312-233314
Keywords A1 Journal article; Condensed Matter Theory (CMT)
Abstract We report quenching of the Hall effect with increasing magnetic field confined in a micron-sized spot. Such fields were created by placing tall ferromagnetic pillars on top of a two-dimensional electron gas, which allowed us to achieve the field strength up to 0.4 T under the pillars in the absence of external field. The quenching is accompanied by an anomalous increase in resistance and occurs when the cyclotron diameter matches the size of the magnetic spot. The results are explained by a rapid increase in the number of electrons that are scattered or quasilocalized by the magnetic region.

Title Precision magnetometry on a submicron scale: magnetisation of superconducting quantum dots Type A1 Journal article
Year (down) 1998 Publication Superlattices and microstructures Abbreviated Journal Superlattice Microst
Volume 23 Issue 1 Pages 151-160
Keywords A1 Journal article; Condensed Matter Theory (CMT)
Abstract We report on magnetisation of individual superconducting particles with size down to 0.1 micron. The non-invasive access to properties of such small objects has become possible using submicron Hall probes which detect a local magnetic field and work effectively as micro-fluxmeters similar to, e.g., SQUIDs but with an effective detection loop of only about a square micron. We have found that the spatial confinement of superconductivity in a small volume gives rise to dramatic changes in thermodynamic properties of mesoscopic superconductors.
