kerr materials 中文意思是什麼
-
In the second chapter, we explain the basic knowledge on magneto - optic effect and the progress of the magneto - optic materials in detail. first, the theory of faraday effect, magnetic circular dichroism, magnetic linear birefringence and kerr effect are argued. then the kinds of the magnetic materials and the magneto - optical devices are discussed
在磁光理論部分，分別對faraday效應與磁致圓二向色性、磁致線雙折射與線二向色性、磁致克爾效應等磁光效應進行了理論推導與分析；在磁光晶體部分，對磁性材料的分類及部分重要的磁光器件進行了介紹。 -
Hysteresis loop of ferromagnetic materials are measured by using surface magneto - optic kerr effect, and the kerr rotation angle is obtained
摘要用表面磁光克爾效應測量鐵磁材料的磁滯回線，並求得在飽和狀態下的克爾旋轉角。 -
And the dopping magneto - optical materials were constructed to better meet the demand for the properties of magneto - optical disk recording media materials, forming the series magneto - optical recording media materials and decreasing the making cost by the method of introducing the light and middling rare - earth into the tbfeco materials. the magneto - optical properties and compositions of the tb - fe - co series dopping magnetic - optical film materials were investigated. the results show that when small amount of adulteration element was introduced into the tb - fe - co, the magneto - optical properties of materials are increased. for example the kerr angle and the coercive force are both improved
對輕、中稀土摻雜的tb - fe - co系列磁光薄膜材料進行丁磁光性能和成分的測試，結果表明：在摻雜元素含量較小時，摻雜后的tb - fe - co磁光材料具有較好的磁光性能， kerr轉角_ k和矯頑力hc都有所改善，摻雜元素的含量應嚴格控制，不能超過一定限度，一般一般摻入量應莊10at左右。
