摘　　要：　采用柠檬酸络合物型溶胶 凝胶法首次制备得到了具有垂直各向异性的(BiAl)DyIG石榴石磁光记录薄膜,并对材料结构和磁光性质进行了研究,结果得到石榴石磁光记录薄膜磁滞回线具有较好的矩形比,在430nm和520nm的品质因子为2°和1.5°,最佳晶化温度为675℃。In this work (BiAl)DyIG films with perpendicular magnetic anisotropy were prepared on glass substrates by citric acid complex type sol-gel method. The structure and magneto-optical properties were investigated. The Kerr hysteresis loops exhibit good square shape. The figures of merit were 2° and 1.5° at wavelengths of 430 nm and 520 nm respectively. The best crystallization temperature was 675°C.
