High quality single crystal Bi, Gd: YIG films have been grown on GCMZGG wafers by LPE techniques. The magnetic, magneto-optic and sensor properties of the films have been investigated. The films showed high linearity with almost no hysteresis, saturaton Faraday rotation angle of 45˚, saturation field of about 1.1 kOe, Verdet constant of 5.6˚ /(Oe, ㎝) at room temperature, and temperature coefficient of Verdet constant of 0.0056˚/(Oe, ㎝, ℃) in the range of 0℃ ~ 100℃. The sensor made out of the film exhibited highly linear signal in the range of 3 A-300 A.
