The magnetocaloric effect and the elastocaloric effect in a polycrystalline all-d-metal Ni37Co9Fe4Mn35Ti15 magnetic shape memory alloy are investigated. The alloy undergoes a transition from ferromagnetic austenite to weak-magnetic martensite near room temperature. It exhibits a maximum magnetic entropy change of 8.4 J Kg(-1) K-1 under the magnetic field of 3 T. Moreover, a maximum temperature change of 6.3 K associated martensite transition is obtained at room temperature by loading the uniaxial stress of 400 MPa. These results suggest that the alloy is the promising candidate for new solid-state refrigeration materials.
