The Discussion of Two Kinds of Methods for Measuring the Saturation Magnetization of Garnet Bubble Films
摘要/Abstract
摘要:
用振动样品磁强计(VSM)测量了石榴石磁泡膜的饱和磁化强度M, 并与用磁光法测量的结果进行了比较.发现用两种方法测得的M随温度的升高而下降的趋势存在着明显的差别, 用VSM测得的下降趋势缓慢, 用磁光法测得的下降趋势迅速.这就引出一个问题:与磁光法测量M有关的理论可能存在着不足.
Abstract:
The sturation magnetization(M) of garnet bubble films can be measured by the vibrating sample magnetometer(VSM) or by magneto-optic method. By a comparison between the two results, we found that, with the increase of temperature, the declined trend of M obtained by the two kinds of methods are obvious different. The declined trend of M measured by VSM is slower than that obtained by magneto-optic method.
