Abstract

Abstract: The structural and magnetic properties of amorphous Fe87 − y B13 Cu y ( y = 0 to 1.5) annealed with a range of heating rates (α) up to 150 K/s were investigated. The lowest coercivity ( H c ) for Fe87 B13 after crystallization shows a dramatic decrease from 174 A/m to 6.7 A/m when α is increased from 1.7 K/s to 150 K/s. The coercivity of Fe87 − y B13 Cu y annealed at 150 K/s is reduced by Cu addition and H c = 3.0 A/m is obtained at y = 1.5. Nanostructures with a grain size of 15 to 20 nm were evident in transmission electron micrographs from these rapidly annealed alloys. Graphical abstract:
