Magnetization Reversal in Low-Curie Amorphous Microwires for Wireless Temperature Sensors
摘要
Abstract
The temperature behavior of magnetic hysteresis loops and the harmonic spectrum of induced voltage in amorphous microwires with different magnetic anisotropy have been investigated. The type of magnetic anisotropy retains up to the Curie temperature. The analysis of the harmonic spectrum has revealed a decrease in the amplitudes of odd harmonics, proportional to the saturation magnetization, near the Curie temperature.
