• Low temperature x-ray diffraction, martensitic transition.
• Near room temperature giant inverse magnetocaloric effect.
• Giant negative magnetoresistance.
Structural, magnetic, magnetotransport, and magnetocaloric effect of Heusler alloy Ni48.4Co1.9Mn34.2In13.8Ga1.7 have been studied. X-ray diffraction study at different temperatures and magnetothermal measurements performed at different applied magnetic fields reveal a transition from ferromagnetic state to a low magnetization state around 300 K, while the temperature is being decreased, is related to the austenite–martensitic structural transition. Near room temperature giant inverse magnetocaloric entropy change 18 J/kg-K and giant negative magnetoresistance (−66%) for 70 kOe magnetic field change have been observed around the first order magnetostructural transition.
