Faraday effect magneto optic optical fiber current sensor offers certain advantages in simple configuration,safety,high accuracy and sensibility,much attention were focused on both domestic and abroad.Magneto optic properties of Faraday sensing element has much affect on the performance of the Optic Fiber Current Sensor.In this work,magnetooptic single crystal garnet BiGd:YIG with high Faraday rotation and low temperature sensibility was growth from high temperature flux.Magneto optic properties in near infrared range were measured.The specific Faraday rotation θ F were -534 °/cm(at λ=1.31 μm) and -441 °/cm(at λ=1.55 μm),much higher than pure YIG's.Its Faraday rotation has low temperature dependence,the temperature sensibility is 4.20×10 -4 (K -1 ) among 250~400 K.Used this crystal garnet as sensing elements,the magneto optic current sensor had the sensibility of 4 /m and accuracy of ±0.3%.
