Abstract
- Magnetostructural transition and the associated magnetocaloric effect were investigated for Mn 1− x Ni 1− x Co 2 x Si 1− x Ge x system. Co and Ge co-substitution drastically reduces the structural transition temperature from 1200 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 Mn 1− x Ni 1− x Co 2 x Si 1− x Ge x system can be an attractive platform for the tunable magnetostructural transition and the magnetocaloric effect.
