Scanning tunneling microscopy study of Ni2MnGa(100) surface
Jayita Nayak, Abhishek Rai, D. L. Schlagel +2
Ni2MnGa(100) surface has been investigated in the premartensite and martensite phase by using scanning tunneling microscopy. The presence of twined morphology is observed in the pr…
CoPtGa: A promising magnetic shape memory alloy with high martensite transition temperature
Tufan Roy, P. Devi, Sanjay Singh +2
In the present work, a combined theoretical and experimental study on CoPtGa Heusler alloy shows that it exhibits a martensite transition around 1320 K with a small thermal h…
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…
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…
Incommensurate modulations in stoichiometric Ni2MnGa ferromagnetic shape memory alloy: An overview
Sanjay Singh, S. R. Barman, D. Pandey
This article presents a brief overview of our recent work on the nature of long period modulation in the premartensite and martensite phases of Ni2MnGa ferromagnetic shape memory a…
A high resolution synchrotron x-ray powder diffraction study of the incommensurate modulation in the martensite phase of Ni2MnGa: Evidence for nearly 7M modulation and phason broadening
Sanjay Singh, V. Petricek, Parasmani Rajput +4
The modulated structure of the martensite phase of Ni2MnGa is revisited using high resolution synchrotron x-ray powder diffraction (SXRPD) measurements, which reveals higher order…
