详细研究了Ｃｏ３４Ｃｕ６６颗粒膜在不同退火温度下的磁光性质．结果表明：未退火时在测量的能量范围内，位于３．８ｅＶ处有一θｋ峰．随着退火温度的升高，θｋ有不同程度的增加，当退火温度高于２００℃时，可以观察到在２．１ｅＶ附近出现一个θｋ的增强峰．其中２．１ｅＶ处的峰来源于Ｃｕ的带间跃迁，３．８ｅＶ处的峰来源于Ｃｏ．面内和极向Ｋｅｒｒ回线的测量表明：经退火后Ｃｏ颗粒变成平行于膜面的盘状
The magneto-optical properties of Co34Cu66 granular films at different annealing temperatures were studied in detail. The results show that there is a θk peak at 3.8 eV within the energy range of the measurement without annealing. As the annealing temperature increases, θk increases to some extent. When the annealing temperature is higher than 200 ℃, an enhanced peak at θe of 2.1eV can be observed. Among them, the peak at 2.1 eV originated from the band transition of Cu, and the peak at 3.8 eV originated from Co. Measurement of in-plane and poloidal Kerr loops showed that Co-particles annealed to disk-like shape parallel to the membrane surface
