What is gyromagnetic material

- Mar 15, 2018 -

The gyromagnetic material has unique microwave magnetic properties, such as properties, permeability tensor Faraday rotation, resonance absorption, field shift, phase shift, birefringence and spin wave effect. The devices made from the gyromagnetic material is mainly used for microwave energy transmission and conversion, used a circulator, isolator, filter (fixed or electric), attenuator, phase shifter, modulator, switch, limiter and delay line, and still developing magnetic surface waves and magnetostatic wave devices. Commonly used gyromagnetic material materials have been formed in series, including Ni, Mg, Li, YlG and BiCaV systems. They can be made into single crystal, polycrystalline, amorphous or thin films with different structures and forms according to the needs of devices.
