Coercive Force of Single-Crystal GdIG as a Function of Temperature

Abstract

Intrinsic coercive force data for both single-crystal and polycrystalline gadolinium iron garnet (GdIG) are presented. Measurements near the magnetization compensation temperature (TCM) are stressed, and an explanation for the single peak in the intrinsic coercive force based on magnetization reversal by domain rotation rather than wall motion is proposed.
