Title: First-principles calculation of the electronic structure of yttrium iron garnet (Y{sub 3}Fe{sub 5}O{sub 12})

Abstract

The electronic structure of Y{sub 3}Fe{sub 5}O{sub 12} (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 -0.62{mu}{sub B} and +1.56{mu}{sub B} 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 e{sub g} and t{sub 2g} levels for the spin-up and spin-down electrons.
