从理论和实验上分析了Ｆｅ３＋和Ｆｅ２＋对（ＢｉＡｌ）ＹＩＧ薄膜的生长感生磁各向异性的贡献．掺Ｂｉ导致的生长磁感生各向异性，来源于Ｂｉ（３＋）改变了Ｆｅ（３＋）的零场劈裂，其大小取决于Ｂｉ（３＋）含量及在十二面体位的择优分布．高价离子和氧空位形成的ＦＣ（２＋）在八面体位的择优分布，对生长感生磁各向异性也有贡献．
The contributions of Fe3 + and Fe2 + to the magnetostriction anisotropy of (BiAl) YIG films were analyzed theoretically and experimentally. Magnetoelastic anisotropy of growth due to Bi incorporation is derived from Bi (3+) changing the zero-field splitting of Fe (3+), which depends on the Bi (3+) content and the preferential distribution in the dodecahedral. The preferential distribution of FC (2+) formed by high-valent ions and oxygen vacancies in octahedral sites also contributes to the growth-induced magnetic anisotropy.
