چکیده انگلیسی
Magnetostructural transition and the associated magnetocaloric effect were investigated for Mn1âxNi1âxCo2xSi1âxGex system. Co and Ge co-substitution drastically reduces the structural transition temperature from 1200Â K to below room temperature. The magnetostructural transition occurring between a ferromagnetic and a paramagnetic state with a sharp jump in magnetization was realized, which is tunable in a broad Curie-temperature window spanning room temperature by altering the composition. Relatively large magnetic entropy changes and broad working temperature ranges were observed. These results suggest that the Mn1âxNi1âxCo2xSi1âxGex system can be an attractive platform for the tunable magnetostructural transition and the magnetocaloric effect.
