摘要
用ｒｆ溅射方法在玻璃衬底上制备了Ｂｉ置换ＤｙＩＧ薄膜。研究了λ＝５１０ｎｍ时在膜面上蒸镀Ｃｒ层后磁光膜的干涉作用。为获得最佳载噪比，给出两层膜结构盘片的最佳设计和最佳读出激光功率。
Bi substituted DyIG films were prepared on glass substrates by conventional rf sputtering.Theinterference of magnet0-optical thin films is investigated at λ=510nm when the surface of films is de-posited with Cr. The optimum design of the disk with two layer structure are presented for obtainingthe optimum ratio of reproduced signal to noise and the optimum reading laser power.
