Abstract

掺杂量增加呈线性变化, Bi 3+ 掺杂量每增加 1% (原子分数), 在波长 1064 nm 和 1550 nm 处变化量分别约为-49.0(°)/cm 和-30.2 (°)/cm。 Bi 0.6 Y 2.4 Fe 5 O 12 陶瓷样品在 1064 nm 和 1550 nm 波长下法 拉第旋转角分别达到-703.3 (°)/cm 和-461.5 (°)/cm, 绝对值远高于未掺杂 YIG 陶瓷的 277.6 (°)/cm 和 172.0 (°)/cm。 由此可见, 掺杂适量 Bi 3+ 可以显著增强 YIG 陶瓷材料的磁光性能。 关 键 词: 钇铁石榴石; 磁光陶瓷; 铋掺杂; 红外透光率; 法拉第旋转 中图分类号: TM284 文献标志码: A 无 机 材 料 学 报 第 37 卷 changes about -49.0 (°)/cm and -30.2 (°)/cm at 1064 nm and 1550 nm wavelengths, respectively.Faraday rotation angles of Bi 0.6 Y 2.4 Fe 5 O 12 ceramic sample at wavelengths of 1064 nm and 1550 nm are -703.3(°)/cm and -461.5 (°)/cm, respectively, which are much higher than that of the undoped YIG ceramics (277.6 (°)/cm and 172.0 (°)/cm, respectively).The magneto-optical performance of YIG ceramics is enhanced obviously by the Bi 3+ doping.
