Magnetocaloric properties and magnetic cooling performance of low-cost Fe75 − xCrxAl25 alloys

Magnetocaloric properties and magnetic cooling performance of low-cost Fe75 − xCrxAl25 alloys

Low-cost, earth-abundant magnetocaloric materials (MCMs) are required for energy-efficient, green, and affordable magnetic cooling technology. We investigated the magnetic and magnetocaloric properties of rare-earth-free Fe75−xCrxAl25 (19≤x≤25) arc-melted alloys. The Curie temperature (Tc) of these...
