  • Abstract
    We have studied the magnetocaloric effect in high energy ball milled (Fe70Ni30)95Mn5 alloy nanoparticles. The partial substitution of Fe and Ni by Mn decreases the Curie temperature of the alloy to near room temperature (338 K). Relative cooling power (RCP) increases from 26 to 470 J-kg-1 for a field change of 0.5 and 5 T, respectively, these values are comparable to the benchmark magnetocaloric material, gadolinium.
