Abstract

The magnetocaloric response of mechanically alloyed Fe75 Nb 10 B15 powders was studied for samples with different amorphous and nanocrystal volume fractions. Thermomagnetic properties scale following a Ω3 law for different milling processes, where Ω is the milling frequency. Curie temperature of the amorphous phase increases as the amorphous fraction increases due to its progressive enrichment in B. The peak magnetic entropy change, |Δ SM pk| , as well as the refrigerant capacity increase with increasing amorphous fraction. The field dependence of |Δ SM pk| can be explained by the multiphase character of the studied samples.
