The amorphous alloy where heat resistance is superior thin the band and this amorphous alloy thin the high heat-resistant magnetic part null magnetostriction which

摘要

PPROBLEM TO BE SOLVED: To provide an amorphous alloy thin band excellent in heat resistance of which magnetic characteristics changes less even under high temperature, and a high-resistant magnetic component. PSOLUTION: Grooves are formed on at least one surface of amorphous alloy thin band whose magnetostriction is almost zero. The grooves define a plurality of divided surfaces on the surface of amorphous alloy thin band, resulting in the amorphous alloy thin band with excellent heat resistance. The amorphous alloy thin band with excellent heat resistance constitutes a heat-resistant magnetic component. PCOPYRIGHT: (C)2006,JPO&NCIPI
