摘要
Devitrification of Co-based amorphous alloys, enhanced initial permeability and giant magneto-impedance have been studied for the samples of composition, Co68Fe4Ni1Si15B12, Co67Fe4Ni2Si15B12 and Co67Fe4Mo2Si15B12. Ultra-soft magnetic properties has been observed by appropriate annealing manifested by high initial permeability of the order of 10(4) and low relative loss factor of 10(-6). Giant magneto-impedance ratio (GMIR) has been obtained for these compositions measured with a current driving frequency of 4.5 MHz. Field dependence of GMIR response varies for different composition and annealing condition.
