Electronic structure of Cu in ferromagnetic CaCu3Sn4O12

We have investigated the electronic structure of Cu ions in ferromagnetic compound CaCu3Sn4O12 by using X-ray absorption and magnetic circular dichroism (MCD) measurements around the Cu L3,2- and O K-edges. In both edges, the signal of MCD were clearly observed. By using sum rules, we could obtained...

Description
Summary:We have investigated the electronic structure of Cu ions in ferromagnetic compound CaCu3Sn4O12 by using X-ray absorption and magnetic circular dichroism (MCD) measurements around the Cu L3,2- and O K-edges. In both edges, the signal of MCD were clearly observed. By using sum rules, we could obtained Mspin = 0.87 ± 0.01 μB, Morb = 0.07 ± 0.01 μB, and Mtotal = 0.93 ± 0.02 μB per Cu ion. The orbital magnetic moments of Cu ions are significant and are originated from the spin-orbit interactions.
