Residual stress induced stabilization of martensite phase and its effect on the magneto-structural transition in Mn rich Ni-Mn-In/Ga magnetic shape memory alloys
Sanjay Singh, Pallavi Kushwaha, F. Sceibel +5
The irreversibility of the martensite transition in magnetic shape memory alloys (MSMAs) with respect to external magnetic field is one of the biggest challenges that limits their…
Large ground state magnetic moment and magnetocaloric effect in Ni2Mn1.4In0.6
Sanjay Singh, Luana Caron, S. W. DSouza +6
A large conventional magnetocaloric effect at the second order magnetic transition in cubic Ni2Mn1.4In0.6 Heusler alloy is reported. The isothermal magnetization at 2K shows a huge…
Premartensite to martensite transition and its implications on the origin of modulation in Ni2MnGa ferromagnetic shape memory alloy
Sanjay Singh, J. Bednarcik, S. R. Barman +2
We present here results of temperature dependent high resolution synchrotron x-ray powder diffraction study of sequence of phase transitions in Ni2MnGa. Our results show that the i…
