Half-metallic antiferromagnets in double perovskites: LaAVRuO$_6$ (A=Ca, Sr, and Ba)

, 2001
Based on the theoretical exploration of electronic structures, we propose that the ordered double perovskites LaAVRuO$_6$ and LaVO$_3$/ARuO$_3$ (001) superlattice (A = Ca, Sr and Ba) are strong candidates for half-metallic (HM) antiferromagnets (AFMs ...

Topological magnetic phase in LaMnO$_3$ (111) bilayer

, 2015
Candidates for correlated topological insulators, originated from the spin-orbit coupling as well as Hubbard type correlation, are expected in the ($111$) bilayer of perovskite-structural transition-metal oxides. Based on the first-principles calculation

X-ray magnetic circular dichroism study of Re 5d magnetism in Sr2CrReO6

, 2005
We have measured Re 5d spin and orbital magnetic moments in the ferrimagnetic double perovskite Sr2CrReO6 by X-ray magnetic circular dichroism at the L_{2,3} edges. In fair agreement with recent band-structure calculations [Vaitheeswaran et. al., Ref 1],
