Description

The electronic structure of Y3Fe5O12 (YIG) crystal was calculated using the spin-polarized orthogonalized linear combination of atomic orbitals method in the local spin-density approximation. It is shown that YIG has a ferrimagnetic ordering with Fe spin magnetic moments of -0.62μB and +1.56μB at the octahedral 16(a) site and the tetrahedral 24(d) site, respectively. The origin of ferrimagnetism in the two Fe sublattices can be traced to the different ordering of the eg and t2g levels for the spin-up and spin-down electrons.
