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.
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.
