Pavlyk L. Reversible magnetization reversal usage in the fluxgate-type magnetic field transducers

The thesis is devoted to investigation of the usage of coherent magnetization reversal of the soft magnetic films as a core of the fluxgate-type magnetic field transducer based on magnetization reversal of the core by the field rotating in the core's plane. The method of controlling of the transducer excitation fielsd shape was developed. Optimal conditions for excitation and registration of the transducer response signal were determined. Voltage powered mode of magnetic field transducer was investigated as well as a transducer based on magnetization reversal of the core by the field performing rotational vibrations in the plane of the core was developed. The method of its sensitivity enhancement was proposed.
