Abstract

The changes in the domain structure of CoNi microparticles under action of mechanical stresses have been studied. With this purpose, an array of identical planar square CoNi particles has been formed on the surface of a polished glass substrate. An elastic bending of the substrate has been used to induce mechanical stresses in the particles. It is shown, using magnetic-force microscopy, that the magnetic structure of the particles can be changed from the multidomain to quasi-homogeneous magnetization using mechanical stresses.

通过机械应力控制CoNi微粒的磁性结构

摘要

研究了在机械应力作用下CoNi微粒的畴结构变化。为此目的，已经在抛光的玻璃基板的表面上形成了相同的平面正方形CoNi颗粒的阵列。基底的弹性弯曲已被用来在颗粒中引起机械应力。使用磁力显微镜显示，可以利用机械应力将颗粒的磁性结构从多畴变为准均质磁化。
