“Giant magnetoresistance in the half-metallic double-perovskite ferrimagnet Mn2FeReO6”. Li MR, Retuerto M, Deng Z, Stephens PW, Croft M, Huang Q, Wu H, Deng X, Kotliar G, Sánchez-Benítez J, Hadermann J, Walker D, Greenblatt M;, Angewandte Chemie: international edition in English 54, 12069 (2015). http://doi.org/10.1002/anie.201506456
Abstract: The first transition-metal-only double perovskite compound, Mn2+ Fe-2(3+) Re5+ O-6, with 17 unpaired d electrons displays ferrimagnetic ordering up to 520K and a giant positive magnetoresistance of up to 220% at 5K and 8 T. These properties result from the ferrimagnetically coupled Fe and Re sublattice and are affected by a two-to-one magnetic-structure transition of the Mn sublattice when a magnetic field is applied. Theoretical calculations indicate that the half-metallic state can be mainly attributed to the spin polarization of the Fe and Re sites.
