Abstract

A new type of magnetic field sensor based on creation of the Faraday effect by rotation magnetization of YIG single crystals is described. The influences of both the Cotton-Mouton effect and cubic anisotropies on the sensor characteristics are also discussed. The linearity error of the sensor output was very small in external magnetic fields ranging of 0.02-200 Oe. The temperature dependence of the sensor output was obtained with an accuracy of ± 1 % between 20 °C and 120 °C.
