Abstract
Co71Mo9P14B6 bulk glassy rod with a maximum diameter of 4.5mm is fabricated by combining fluxing treatment and J-quenching technique, and its magnetocaloric effect (MCE) has been investigated in the present work. The peak values of the magnetic entropy change and refrigerant capacity of the Co71Mo9P14B6 bulk metallic glass (BMG) are 0.96Jkg−1K−1 and 70.5Jkg−1, respectively, under a maximum applied field of 5T. Most importantly, this BMG exhibits a Curie temperature of 317K, which is suitable for room-temperature magnetic refrigeration. Combining the large glass-forming ability and near room-temperature MCE, the present Co71Mo9P14B6 BMG provides a candidate used as near room-temperature magnetic refrigerant.
