研究了磁性薄膜磁场电效应的测试方法，ＲＥ－ＴＭ磁光薄膜的测试样品制备、样品的磁场电效应（霍尔效应和磁阻效应）及其温度特性。实验结果表明，制备的ＴｂＦｅＣＯ薄膜的补偿点约为─３８℃。
The test method of the magnetic field effect of the magnetic thin film, the preparation of the test sample of the RE-TM magneto-optical thin film, the magnetic field effect (Hall effect and magnetoresistance effect) and the temperature characteristic of the sample are studied. The experimental results show that the compensation point of the prepared TbFeCO film is about -38 ℃.
