摘要
介绍了一种精确测量磁性薄膜磁致伸缩系数方法———电容位移法 ,并自行研制组装了一套测量装置 ,通过误差分析、仪器的精确标定 ,对稀土 铁超磁致伸缩薄膜的磁致伸缩系数进行了测量 。
A method for testing the magnetostriction coefficient of thin film accurately was presented in this paper. The thin film and the sensor of the testing equipment constructed a capacitance. By confirming the relationship between the capacitance and the displacement of the cantilever film, the magnetostriction coefficient of the film could be calculated accurately. The giant magnetostriction of TbDyFe prepared by magnetron sputtering was tested and the results were satisfied.
