Abstract
, Bi 3+ 1% (), 1064 nm 1550 nm -49.0 ()/cm -30.2 ()/cm Bi 0.6 Y 2.4 Fe 5 O 12 1064 nm 1550 nm -703.3 ()/cm -461.5 ()/cm, YIG 277.6 ()/cm 172.0 ()/cm , Bi 3+ YIG : ; ; ; ; : TM284 : A 37 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.
