Influence of Jahn-Teller Ions on Spin-Lattice Relaxation in Ferrimagnets

摘要

Spin-lattice relaxation in ferrites can be enhanced by 3d~n ions with t_(2g) orbital Jahn-Teller effect capabilities. When exchange-ordered, Mn~(3+), Fe~(2+), Co~(2+), Cu~(2+) can stabilize orbital doublets from the t_(2g) shell by spin-orbit interactions. This occurrence can also account for observed magnetoelastic effects.
