چکیده انگلیسی
Giant magnetoimpedance (GMI) effect has been measured in a glass-coated amorphous (Co0.93Fe0.7)63Ni10Si11B16 microwire as a function of DC magnetic field and up to the frequency of 11Â MHz. The sample shows single peak GMI characteristics within the whole range of frequency. The domain structure of the above sample has been changed by applying tensile stresses up to 603Â MPa and current annealing with a DC current of 50Â mA for various time durations, and the corresponding effect on GMI has been studied in detail. A maximum change of 8.85% in MI of the as-quenched sample has been observed around a frequency of 5.05Â MHz. Application of an external tensile stress reduces the GMI value by increasing the inner core domain, whereas heat treatment of the sample enhances the same. The square-shaped magnetic hysteresis loop of the as-quenched sample helps us understanding the MI results.
