摘      要：The barocaloric effect(BCE)is a promising alternative to traditional vapor compressing refrigeration because of its environmentally friendly impact and high energy ***,the driving hydrostatic pressure for most BCE materials is relatively high,which is not conducive to practical *** this paper,we report that the large barocaloric entropy change of MnAs_(0.94)Sb_(0.06)alloy can be induced by low hydrostatic *** phase transition temperature is strongly sensitive to the applied pressure,resulting in a large barocaloric coefficient of 134 K·GPa^(-1)on cooling and 126 K·GPa^(-1)on *** maximum barocaloric entropy change and adiabatic temperaturechange resulted from hydrostatic pressure of 40 MPa reach up to 26.3 J·kg^(-1)·K^(-1)and 14.4 K,respectively,showing an excellent barocaloric *** results demonstrate that the MnAs_(0.94)Sb_(0.06)alloy is a promising alternative for BCE refrigeration.
