A novel behaviour of dynamic magnetization process in gold-plated CoFeSiB amorphous wires

摘要

Dynamic magnetization processes in CoFeSiB amorphous wires with bamboo domain structures have been studied with observations of ac voltage-current relations of the wires depending on dc bias magnetic fields. A novel behaviour of the dynamic magnetization processes is found in the gold-plated wires. This novel behaviour is useful for improvement of performances in magnetic-field-sensing devices using the wires.
