Tb/Fe成分调制膜的磁特性

Tb/Fe成分调制膜的磁特性 MAGNETIC PROPERTIES OF Tb/Fe COMPOSITIONALLY MODULATED FILMS 周正国 Zhou Zhengguo and Zhou Dianqing first-author 周殿清 本文研究了用电子束蒸发法制作的Tb/Fe成分调制膜的磁特性,讨论了膜厚与饱和磁化强度及磁各向异性的关系。我们发现:该材料有饱和磁化强度不为零的极小值成分点。在成分点附近,磁各向异性变化显著。可预示这是一种很有应用前景的新的光磁材料及电磁材料。 In this papes, we investigated magnetic properties of Tb/Fe compositionally modulated films prepared by electronic—beam sputtering, and discussed film thickness dependences of the magnetization M, and the magnetic anisotropy K u . We found out that there is a minimum composition point where the saturation magnetization is not equal to zero, and that the values of Ku change sharply in the vicinity of the point. It is presumable that the material is a very promising new magneto—optical and electro—magnetic meterial. 调制膜 补偿点 饱和磁化强度 各向异性 1987-03-01 2021-04-01 3
