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

Differentiating between perovskite and double perovskite nanocrystals
, 2023 Perovskite structure takes the empirical formula ABX3, whereas Double perovskites, or elpasolites, are the crystal structures in which the B position in ABX3 is equally occupied by two different cations. The usual compositions of Double perovskite structure are (1-3) type double perovskites, which means that the two B cations have +1 and +3 oxidation ...

Theory of half-metallic double perovskites. I. Double exchange mechanism [PDF]
Physical Review B, 2013 The double perovskite material \SFMO has the rare and desirable combination of a half-metallic ground state with 100% spin polarization and ferrimagnetic \Tc$\simeq 420$K, well above room temperature. In this two-part paper, we present a comprehensive theoretical study of the magnetic and electronic properties of half metallic double perovskites.
