摘要
为了改变Pt/Co多层膜的磁光特性与磁性 ,插入第三元素层是有效途径之一。我们研究表明 ,插入Ni层可导致居里温度Tc 的下降。所插的层最佳厚度为 0 3～ 1 0nm ,X射线衍射实验表明 ,插入Ni层后的样品具有良好的成层结构。Pt(111)峰与Co(111)峰的位置分别比纯Pt/Co相应的峰略向左移和向右移 ,这证明面间距分别是增大和缩小。磁性测定表明 ,由于Ni层的插入磁光克尔角θk 略有增高 。
In order to improve the magneto optical and magnetic properties of Pt/Co multilayer film,to insert the third element layer is one of the effective ways Our studies show that the insert of Ni layer causes the decrease of Curie temperature T c,and the ideal thickness of the inserted layer is 0 3～1 0nm The X ray diffractometry experiment shows that inserted Ni layer sample has good laminated structure The positions of peak Pt(111) and Co(111) slightly move left and right respectively compared with corresponding pure Pt and Co peaks And this proves that interfacial distance is increased and decreased respectively Magnetic property determination indicates that because of the slight increase of magneto optical Kerr angle θ k caused by Ni layer insert,the remanence ratio and coercivity are better
