Description
Co-rich amorphous ribbons with nearly zero magnetostriction are well known for their outstanding giant magnetoimpedance (GMI) sensor characteristics [1,2]. However, their relatively low Currie temperature can be a disadvantage for their application at elevated temperatures. In this work, the effects of temperature on magnetoimpedance response were investigated in stress annealed commercial amorphous VITROVAC® 6025 I50 ribbons. As-quenched ribbons were subjected to tensile stress annealing at 700 MPa and 350
