Temperature Dependence of Minor Hysteresis Loop in NiZn Ferrite Measured by Lock-In Amplifier

摘要

The detailed loop measurements of an NiZn ferrite toroid have been studied at various temperatures below the Curie temperatures using a lock-in amplifier. The Jiles–Atherton (JA) analysis of the loops gives the power-law relations among the hysteresis parameters and the JA parameters. The Steinmetz analysis suggests the power-law relation proposed by Kobayashi is valid in wide range of the temperature in low magnetic field.
