Abstract

The ferrimagnetic semiconductor (FMS) is one type of ferrite belonging to the family of n-type semiconductors with a ferromagnetic property below the Curie temperature. The FMS is a multi-ability device which adds the functions of a magnetostrictive vibrator, a thermistor, a semiconductor capacitor, and a temperature-sensitive magnetic core to a switching element. Techniques for applying the FMS module to protection and supersonic monitor sensors in the thyristor system are discussed
