Abstract

The structural, magnetic and magnetocaloric properties of the antiperovskite materials Mn3CuN1−xCx have been studied. Substituting N with C increases the temperature of the magnetostructural transition between a paramagnetic cubic high temperature phase and a ferrimagnetic tetragonal low temperature phase. Furthermore, the first order character of the phase transition is retained upon substitution with a hysteresis below 2 K for all compositions. The magnetostructural transition gives rise to giant magnetocaloric effects in a tunable 30 K temperature range with a maximum entropy change of 11.8J/Kkg at a 2 T field change, making these compounds promising for low temperature magnetic refrigeration applications.
