在磁光薄膜居里温度的测量中，当薄膜的磁化强度信号与石英试杆和玻璃基片的磁化强度信号具有同一数量级时，石英试杆和玻璃基片对薄膜居里温度的确定引入了很大的误差。提出了消除石英试杆和玻璃基片影响的三种方法。实验结果表明，由三种方法消除石英试杆和玻璃基片影响后所确定得到的磁光薄膜居里温度相对偏差小于5％。因此，三种消除石英试杆和玻璃基片影响的方法是切实可行的。

If the saturation magnetization of? magneto-optical thin film is in th e same order of quantity as the ma gnetization of quartzose holder an d glass substrate， the magnetiza tion of the holder and glass cause s high error in determining Curie? temperature of thin film． Three me thods of eliminating the magnetiza tion of the holder and glass are p resented． The experiment shows tha t the relative error of values of? Curie temperature determined by th e three methods is less than 5％，an d proves the three mathods to be p ractical for eliminating the influe nce of holders and glass substrate ．
