Abstract

Description

The structural and magnetic properties of ball-milled Fe75Cu4Ni4Mo2B15 alloy have been investigated through powder X-ray diffraction studies, magnetization and magnetoimpedance measurements. The particle size decreased rapidly with ball-milling up to 165 hours and then remained as a constant with further hours of milling while, the lattice expanded with milling time up to 165 hours and contracted back with further milling. Saturation magnetization is found to decrease rapidly up to 165 hours of milling and then started decreasing slowly with further milling time. Magnetoimpedance studies were carried out in pellets and thin films of Fe75Cu4Ni4Mo2B15. Magnetoimpedance in pellet is observed to be ~2.5% at 5Hz whereas, in thin films, it is observed to be ~1.5% at 3 MHz.
