The (Co0.35Mno.65)2P compound, prepared by a mechanical alloying plus solid sintering process, exhibits a second-order transition from a ferromagnetic state to a paramagnetic one at Curie temperature of about 320 K with no clear thermal hysteresis. A magnetic-entropy change (△SM) value above 1.6 J.kg-1.K-1 for a 5 T field change is obtained in the whole temperature range of 292.5-352.5 K and the maximum value of the △SM is 2.3 J.kg-1.K-1 at 337.5 K. The study on the magnetocaloric effect of the (Co0.35Mn0.65)2P compound may be helpful for exploring good candidates for room-temperature magnetic refrigeration.
