非晶FeSiBCu合金系的磁后效

Magnetic After-Effect of FeSiBCu Amorphous Alloy System

研究了非晶ＦｅＳｉＢＣｕ合金系的磁后效．结果表明淬态Ｆｅ基非晶合金的磁后效主要来自磁致伸缩相互作用，然而还发现磁后效和感生磁各向异性对Ｃｕ含量有类似的依赖关系，这显示还应考虑感生磁各向异性对磁后效的影响．

The magnetic after-effect of amorphous FeSiBCu alloy system was investigated. The results showed that the magnetic after-effects observed in as-quenched Fe-based alloys are mostly caused by contenttostrictive interaction. However, the magnetic after-effect was found having a dependence on Cu content which is similar to that of induced magnetic anistropy. This implies that the influence of induced magnetic anisotropy on magnetic after-effect should be taken into account.
