Abstract Scope Heusler metamagnetic shape memory alloys (MMSMAs) show a large functional response related to a first order martensitic transformation (MT). The strong magnetostructural coupling together with mixed magnetic interactions (ferromagnetic, antiferromagnetic or paramagnetic) enable controlling the MT by means of magnetic field resulting in different multifunctional properties such as giant magnetoresistance, MMSM effect, or inverse magnetocaloric effect. Both the shift rate of MT as a function of the magnetic field and its eventual suppression are key parameters for the development of all these effects. In this work we have used strong steady magnetic fields, up to 33 T, to study in detail the magnetic field induced MT and its arrest in NiMnIn, MnNiSnFe and NiMnTiCo MMSMAs, resulting in the T-H phase diagrams of the MT. Moreover, we have analyzed the impact of the suppression of the magnetostructural transformation in different functional properties, like magnetocaloric and magnetodeformation effects.
