Abstract

A first order structural transformation occurs in the Ni ₅₀Mn ₃₄In ₁₄Fe ₂ polycrystalline, associated with magnetic entropy changes of 26.5 and 53.6 J/kg K in an applied magnetic field up to 5 and 8 T, respectively. Moreover, the magnetic entropy change with different applied fields maintains its maximum value within a temperature of 3 K. A phase transformation change of 2 K was obtained under 5000 Oe magnetic field, indicating that it is large enough for inducing a reverse martensitic transformation under large magnetic field. All the results mentioned above are favorable for the application of this intelligent intermetallic material.
