Magnetic, transport, and magnetocaloric properties of boron doped Ni-Mn-In alloys
The impact of B substitution in Ni50Mn35In15-xBx Heusler alloys on the structural, magnetic, transport, and parameters of the magnetocaloric effect (MCE) has been studied by means of room-temperature X-ray diffraction and thermomagnetic measurements (in magnetic fields (H) up to 5T, and in the temperature interval 5-400K). Direct adiabatic temperature change (ΔTAD) measurements have been carried out for an applied magnetic field change of 1.8T. The transition temperatures (T-x) phase diagram has been constructed for H=0.005T. The MCE parameters were found to be comparable to those observed in other MCE materials such as Ni50Mn34.8In14.2B and Ni50Mn35In14X (X=In, Al, and Ge) Heusler alloys. The maximum absolute value of ΔTAD=2.5K was observed at the magnetostructural transition for Ni50Mn35In14.5B0.5.
