Influence of Cr substitution on the reversibility of the magnetocaloric effect in Ni-Cr-Mn-In Heusler alloys

We present the effect of substitution-induced pressure on the reversibility of the magnetocaloric effect (MCE) in {\mathrm{Ni}}_{2}{\mathrm{Cr}}_{x}{\mathrm{Mn}}_{1.4\ensuremath{-}x}{\mathrm{In}}_{0.6}(x=0.1 0.2, 0.3) alloys, through characterization in pulsed magnetic fields. We measured the adiabatic temperature change \mathrm{\ensuremath{\Delta}}{T}_{\text{ad}}directly during applied magnetic field pulses of 2 and 6 T. We paid...
