摘要
分别用电桥法、感应法和振动样品磁强计对锰锌铁氧体的居里温度和饱和磁化强度进行了测试。用同一个样品不同的测量方法测量的结果示出,用振动样品磁强计测出的居里温度和饱和磁化强度的数值总高于用电桥法和感应法测出的数值。对于造成这种差别的原因进行了分析,并发现差别的大小有一定的规律性。
The Curie temperature and saturation magnetization of manganese-zinc ferrite were measured by using the electric bridge method, induced method and vibrating sample magnetometer (VCM). The results indicated that the values of Curie temperature and saturation magnetization measured by VCM are always larger than those measured by electric bridge and induced methods for the same sample. The reasons produced this difference were analyzed. We find that the size of difference exists a certain role.
