摘要： 本文论述(BiTm)3(FeGa)5O12膜的液相外延和磁光特性.研究了外延工艺对膜的生长速率和磁光性能的影响,得到膜的磁光优值θF/α达2.9deg/dB,并观察了膜的磁畴结构和内部缺陷.对该薄膜制成的磁光调制器进行了低频调制试验.

Abstract: Liquid phase epitaxy and magneto-optic properties of the films of (BiTm)3(FeGa)5O15 are described in this paper. The influence of epitaxy on the growth rate and the magneto-optic properties of the films was studied. The high magneto-optic figure of merit, θF/α, of 2.9 deg dB has been obtained. The magnetic domain structures and the defects of the films were observed. We have conducted an experiment of modulation for low frequency on the magneto-optic modulator with fairly good results.
