Influence of film size on giant magneto-impedance effect
暂无分享,去创建一个
The relationship between the magneto-impedance (MI) effect and the size of amorphous FeSiB film is reported in this paper. The MI change ratio of FeSiB film is different for the three samples with different widths, and increases with the increasing of sample length when the width is fixed. Experimental results can be explained in terms of stress anisotropy and different external inductance of the sample.
