Abstract: Abstract Two successive magnetocaloric effects consisting of inverse magnetocaloric effect around martensitic transition and negative magnetocaloric effect around magnetic transition of austenitic phase have been observed in Ni50Mn34In15Al alloy. Large inverse magnetic entropy change ΔSm ( ~ 21.3 J kg−1 K−1), small thermal and magnetic hysteresis of martensitic transition give rise of large net refrigerant capacity ( ~ 152.3 J kg−1) under a magnetic field of 50 kOe, which is comparable with that ( ~ 157.9 J kg−1) of second-order transition. The large combined magnetocaloric effects make the Ni50Mn34In15Al alloy as a promising candidate material for room temperature magnetic refrigeration.
