Ge在MnBiAlGe合金薄膜磁光特性中的作用

Effect of Germanium on the Magneto-Optic Characteristic of the Thin Film Composed by MnBiAlGe Alloy

研究了ＭｎＢｉＡｌＧｅ合金薄膜的磁光特性，并着重探讨Ｇｅ在合金薄膜中组分变化对磁光特性的影响，得出了当Ｇｅ为０．３时，其克尔角可达１．７５°，是很有希望的新型磁光材料．

A study is made on the magnetooptic characteristic of the thin film composed by Mn Bi Al Ge alloy, In this alloy film, Mn, Bi and Al are fixed constituents while Ge is variable one. This is an alloy film with a Kerr angle approaching 1.75° in case x=0.3. It is a hopeful new type magnetooptic material.
