Ferrimagnetism in the double perovskite Ca2FeOsO6: a density functional study

Hongbo Wang, Shasha Zhu, Xuedong Ou +1

Using density functional calculations, we find that the newly synthesized Ca${}_2$FeOsO${}_6$ has the high-spin Fe${}^{3+}$ ($3d^5$)-Os${}^{5+}$ ($5d^3$) state. The octahedral Os${}^{5+}$ io…
