Theoretical prediction and experimental study of a ferromagnetic shape memory alloy: Ga2MnNi
Sudipto Roy Barman,Aparna Chakrabarti,Sanjay Singh,Soma Banik,S. C. Bhardwaj,P. L. Paulose,B. A. Chalke,Aurobinda Panda,A Mitra,A. M. Awasthi +9 more
TL;DR: In this paper, the authors predict the existence of a ferromagnetic shape memory alloy using density-functional theory and show that the martensitic transition is volume conserving that is indicative of shape memory behavior.
Journal ArticleDOI
Structural and electronic properties of Ni 2 Mn Ga
TL;DR: In this article, the equilibrium structure and electronic properties of a ferromagnetic shape memory alloy have been studied for both the martensitic and austenitic phases by the full potential linearized augmented plane wave method.
Journal ArticleDOI
Structural studies of Ni 2+x Mn 1-x Ga by powder x-ray diffraction and total energy calculations
Soma Banik,Rajeev Ranjan,Aparna Chakrabarti,S. Bhardwaj,N. P. Lalla,A. M. Awasthi,Vasant Sathe,Deodatta M. Phase,P. K. Mukhopadhyay,Dhananjai Pandey,Sudipta Roy Barman +10 more
TL;DR: The crystal structure of Ni{sub 2+x}Mn{sub 1-x}Ga has been studied as a function of composition (x) by powder x-ray diffraction.
Journal ArticleDOI
Martensitic transition, ferrimagnetism and Fermi surface nesting in Mn2NiGa
TL;DR: In this paper, the electronic structure of Mn2NiGa has been studied using density functional theory and photo-emission spectroscopy, and the calculated valence band spectrum, the optimized lattice constants and the magnetic moments are in good agreement with experiment.
Journal ArticleDOI
