摘要/Abstract

摘要： 研究了(Bi,Y,Lu)₃(Fe,Ga)₅O₁₂膜的液相外延生长工艺,测量了λ=0.40~0.80μm的室温饱和比法拉弟旋转谱和吸收谱,证实了强磁光活性跃迁的存在并讨论了跃迁的微观缘由.

Abstract: The growth technology of LPE is studied for the films of Bismuth substituted iron garnets. At the wavelengths between 0.40μm and 0.80μm,the saturated Faraday rotation spectrum and optical absorption spectrum have been obtained at room temperature for (Bi, Y, Lu)₃(Fe, Ga)₅O₁₂ LPE films with different Bismuth contents. Results indicate that in the vicinity of wavelength 0.5μm, there are the peaks of the rate of the specific Faraday rotation θ_F and optical absorption coefficient α, thus proving the existence of a strong magnetooptic active transition in this region. The microscopic causes of the transition are discussed.
