Magnetostructural transformation and magnetocaloric effect of Sn-bonded Mn_0.66Fe_0.34Ni_0.66Fe_0.34Si_0.66Ge_0.34 composite.

ABSTRACT: Magnetostructural coupling in MnMX (M = Co or Ni, X = Si or Ge) system attracts considerable attention for the accompanied multi-magnetoresponsive effects. However, due to the large stress generated from the structural transformation, the alloys become shattered or powder-like, hindering the further investigation and their applications. The possible solution is to embed the MnMX powders into metal matrix. In this paper, we choose Mn_0.66Fe_0.34Ni_0.66Fe_0.34Si_0.66Ge_0.34 as a representative of MnMX alloy and produce Mn_0.66Fe_0.34Ni_0.66Fe_0.34Si_0.66Ge_0.34/Sn composite bulk by hot pressing. The magnetostructural-coupled composites exhibit an improved rate of the transf
