Abstract
The magnetic and magnetocaloric properties of a series of Fe-rich FeZrB(Cu) amorphous ribbons were investigated under magnetic field values up to μ0H of 8 T. A correlation between the saturation magnetization and the maximum magnetic entropy change |ΔSMpeak| is clearly evidenced. Although these metallic glasses show relatively low |ΔSMpeak| values (from 3.6 to 4.4 J kg−1 K−1 for μ0ΔH = 8 T), the ΔSM(T) curve broadens upon the increase in μ0ΔH, giving rise to a large refrigerant capacity RC (above 900 J kg−1 for μ0ΔH = 8 T). Using the universal curve method for rescaling the ΔSM(T,μ0ΔH) curves, we found a collapse of the curves around the Curie temperature. However, in the low-temperature range the curves do not match into a single one due to the existence of magnetic frustration.
