Description
Summary:This work is devoted to the experimental investigation of the magneto-optical properties of yttrium-iron garnet used as a sensitive element of a fiber-optical magnetic field sensor. The block diagram of the experimental stand and methods of measurement are described. The magneto-optical effect in some YIG samples with different thickness of epitaxial layer is studied, presence of a magneto-optical properties hysteresis is established and its value is measured. Design recommendations for the developed sensor are given.
