摘要：

In this work, we report room temperature magnetocaloric properties in CrTe1-xSex (0.00 <= x <= 0.10) alloys prepared by a conventional solid-state reaction. The Rietveld refinement of the XRD pattern of CrTe1-xSex showed the emerging of pure hexagonal NiAs structure with P63/mmc (194) space group with increasing Se substitution. Upon mu H-0 = 5 T applied magnetic field, the magnetocaloric effect analysis revealed maximum magnetic entropy change (Delta S-M) in the range 7.9-9.2 J/kg K-1 with a relative cooling power (RCP) value of about 550-694 J/kg. The RCP values exceed the corresponding RCP value of the prototype Gd element near room temperature. The obtained results suggest that CrTe1-xSex (0.00 <= x <= 0.10) alloys is a viable candidate for a room temperature magnetic cooling application.
