本文介绍了一种用于振动样品磁强计(VSM)的高精度振动源。它的频率和振幅高度稳定。由于它的利用,使振动样品磁强计采用绝对法测量的相对精度由原来的5％提高到1％。
This article describes a high-precision vibration source for a vibrating sample magnetometer (VSM). Its frequency and amplitude are highly stable. Due to its use, the relative accuracy of the vibrating sample magnetometer measured by absolute method is increased from 5% to 1%.
