摘要
采用溶胶-凝胶法制备了Bi 0.8 Er 0.1 Ba 0.1 Fe 0.96 R 0.02 Cr 0.02 o3 (R = mn3 +和Co 2+)化合物，并在800℃下烧结2h。两种化合物均呈R3C空间基的菱形体结构。确定了两种化合物的纳米尺度标准。含有mn3 +离子的化合物具有较高的饱和磁化强度和较高的铁磁贡献量。
Structural, Morphological and Magnetic Studies on Sol-Gel Multi-Doped BiFeO3 Compounds
The Bi 0.8 Er 0.1 Ba 0.1 Fe 0.96 R 0.02 Cr 0.02 O 3 (R = Mn 3+ and Co 2+ ) compounds were prepared by the Sol-Gel method and sintered at 800 °C for 2 hours. Both compounds present a rhombohedral structure with R3C space group. The nano-size criteria is confirmed for both compounds. The compound with Mn 3+ ions presents the higher saturation magnetization and the higher amount of ferromagnetic contributions.
