Abstract

This study investigates the magnetic properties and magnetic viscosity of Pr_7.8Fe_75.8Co₅Cr₅B_6.4 ribbons. The alloys are produced by melt spinning in argon atmosphere. X-ray diffraction is used to examine the composition and microstructure of the samples. Magnetization, magnetic moment, remanence, and coercivity measurements are performed using vibrating sample magnetometry. It is shown that by measuring the magnetic moment relaxation, the magnetic memory effect is found for the exchange-coupled hard magnets.
