Abstract Scope Metamagnetic shape memory alloys (MMSMAs) represent a new kind of multifunctional materials that show inverse magnetocaloric effect as a consequence of a magneto-structural transformation (martensitic transformation MT). In this work we report on the effect in the MT and magnetocaloric properties of Ga substitution for Ni in Ni<sub>50</sub>Mn<sub>34</sub>In<sub>16</sub> alloys. Ga substitution induces an increase in the MT from 250 K to 305 K and a reduction of Curie point in the austenite phase. We have analysed the magnetocaloric response associated to the MT and the magnetic phase transition in the austenite phase by estimating the magnetic entropy change and measuring directly the adiabatic temperature change, ΔT<sub>ad</sub>. The alloys present inverse MCE with large values of ∆T<sub>ad</sub> (until 2.7K at ∆H=1.9 kOe) associated with the paramagnetic martensite to ferromagnetic austenite phase transition. Conventional MCE (∆T<sub>ad</sub>=1.2 K under ∆H=9 and 1.9kOe respectively) occurs at the magnetic phase transition in the austenite phase.
