Strong magneto-volume effects and hysteresis reduction in the In-doped (NiCo)2MnGa Heusler alloys
Copyright policy )Strong magneto-volume effects and hysteresis reduction in the In-doped (NiCo)2MnGa Heusler alloys
[objeWe report the effect of high hydrostatic pressure (up to 1.1 GPa) on magnetization and critical tem- peratures of the magnetic and magneto-structural transitions in the off-stoichiometric In-doped (Ni,C- o)2Mn(Ga,In) alloys. The magnetization MM(5 K) of their martensitic phase significantly decreases under pressure and the value of dlnMM(5 K)/dP 1/4 À55 Â 10À3 GPaÀ1 was observed in the Ni41Co9Mn33Ga14In3 alloy. The temperature of structural transition of the alloys from martensite to austenite, TM-A, shows a strong dependence on both pressure (dTM-A/dP 1/4 60 K/GPa) and magnetic field. The complex mutual dependence of TM-A to both pressure and magnetic field produces a remarkable reduction of the transformation hysteresis
