Abstract

We studied giant magnetoimpedance (GMI) effect and magnetic properties of Co_69.2Fe_4.1B_11.8Si_13.8C_1.1 amorphous as-prepared and annealed microwires. We observed that these properties can be tuned by heat treatment. High GMI effect has been observed in as-prepared Co-rich microwires. After appropriate annealing, we can observe fast DW propagation and GMI effect in the same sample. Annealing affects both diagonal and off-diagonal GMI components.
