Abstract
The crystal structure and magnetocaloric effect (MCE) of water-quenched and annealed (Mn0.5Co0.5)65Ge35 alloys were studied in this paper. A CoMnGe-single phase was formed in the water-quenched alloy, and mixture phases of CoMnGe and Mn+2O in the annealed alloy. The annealed alloy has a smaller crystal parameter than the water-quenched alloy. The Curie temperature is 275 and 298 K for the water-quenched and annealed alloys, respectively, which means that the magnetic-transition temperature in this material can be controlled by anneal. In addition, the same magnetic entropy change was found in these two alloys, even though their Curie temperatures have a significant difference.
