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

The detailed BH loop measurements of an NiZn ferrite toroid have been studied at various temperatures below the Curie temperatures T C using a lock-in amplifier. The Jiles-Atherton (JA) analysis of the BH loops gives the power-law relations among the hysteresis parameters and the JA parameters. The...

Zusammenfassung:The detailed BH loop measurements of an NiZn ferrite toroid have been studied at various temperatures below the Curie temperatures T C using a lock-in amplifier. The Jiles-Atherton (JA) analysis of the BH 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 et al. is valid in wide range of the temperature in low magnetic field.
