Abstract

Ferrimagnetic iron garnet crystals form the basis of magnetooptic magnetic field sensors which offer high sensitivity, broad-band frequency response, and compatibility with fiber optics. Recent developments at NIST promise still greater performance for these devices in the near term. Specifically, new designs for magnetic field sensors, electric current sensors, and novel experimental iron garnet compositions demonstrate the potential for significantly improving the performance of these devices
