Abstract: | We have used differential scanning calorimetry and thermometry techniques under applied magnetic field and compressive uniaxial stress to determine isothermal entropy and adiabatic temperature changes that quantify the caloric effects associated with the magnetostructural transition of an Fe49Rh51 alloy. It is found that the transition temperature increases with increasing compressive stress while it decreases for increasing tensile stress. This behavior gives rise to a conventional elastocaloric effect for compressive stresses in contrast to the reported inverse elastocaloric effect for tensile stresses. The combined effect of stress and magnetic field does not lead to a significant increase of the maximum temperature and entropy changes associated with magnetocaloric and elastocaloric effects, but there is a modification of the temperature window where the sample exhibits giant caloric responses. |
