Abstract
The influence of the cryogenic treatment and following annealing on the magneto-impedance properties in Co-based (Co66Fe4B 15Si15) with near-zero magnetostriction and Fe-based (Fe60.8Co20.2Si5B14) with positive magnetostriction amorphous alloys were investigated. The magneto-impedance measurements were made in frequency range from 100 kHz up to 10 MHz. It was found that the cryogenic treatment increases the magneto-impedance effect up to 60-70%. The Co-based alloys with cryogenic treatment kept larger value of the magneto-impedance ratio after annealing.
