Large growth‐induced anisotropy to preferential occupation of the iron sites in garnets

Large growth‐induced anisotropies (Ku) arising from the preferential occupation of Ir4+ on octahedral sites have been measured. For YIG with approximately 0.2 Ir atoms per garnet formula unit and Mg2+ as a charge compensator, values of Ku=+4.5×105 ergs/cm3 have been obtained. The induced anisotropy is proportional to the Ir4+ present as deduced from the optical absorption.
