摘要:

研究了阳极氧化铝膜孔内制备的镍纳米线阵列的剩磁和矫顽力随角度的变化关系。通过比较我们的分析计算与我们的测量,我们得出结论,在这个阵列中的磁化反转驱动的横向壁的成核和传播的装置。一个简单的模型的基础上的一个适应的Stoner-Wohlfarth模型被用来解释的角度依赖性的bavity。

英文摘要:

The angular dependence of the remanence and coercivity of Ni nanowire arrays produced inside the pores of anodic alumina membranes has been studied. By comparing our analytical calculations with our measurements, we conclude that the magnetization reversal in this array is driven by means of the nucleation and propagation of a transverse wall. A simple model based on an adapted Stoner-Wohlfarth model is used to explain the angular dependence of the coercivity.
