Nowadays,searching for the materials with multiple magneto-functional properties and good mechan-ical properties is vital in various fields,such as solid-state refrigeration,magnetic actuators,magnetic sensors and intelligent/smart devices.In this work,the magnetic-field-induced metamagnetic reverse martensitic transformation (MFIRMT) from paramagnetic martensite to ferromagnetic austenite with multiple magneto-responsive effects is realized in Fe-doped Co-V-Ga Heusler alloys by manipulating the magnetic ordering.The martensitic transformation temperature Tm reduces quasi-linearly with increas-ing Fe-content.In strikingly contrast with the Fe-free alloys,the magnetization difference (△M\') across martensitic transformation increases by three orders of magnitude for Fe-doped alloys.The increased△M\'should be ascribed to the reduction of Tm,almost unchanged Curie temperature of austenite and the increased magnetic moment in the samples with higher Fe-content.The large △M\'provides strong driving force to realize the MFIRMT and accordingly multiple magneto-responsive effects,such as mag-netocaloric,magnetoresistance and magnetostriction effects,Meanwhile,giant Vickers hardness of 518 HV and compressive strength of 1423 MPa are achieved.Multiple magneto-responsive effects with exceptional mechanical properties make these alloys great potential candidates for applications in many fields.
