Theoretical prediction and experimental study of a ferromagnetic shape memory alloy: Ga_2MnNi
S. R. Barman, Aparna Chakrabarti, Sanjay Singh +7
We predict the existence of a new ferromagnetic shape memory alloy Ga_2MnNi using density functional theory. The martensitic start temperature (T_M) is found to be approximately pr…
Magnetoresistance behavior of a ferromagnetic shape memory alloy: Ni_1.75Mn_1.25Ga
S. Banik, R. Rawat, P. K. Mukhopadhyay +7
A negative-positive-negative switching behavior of magnetoresistance (MR) with temperature is observed in a ferromagnetic shape memory alloy Ni_1.75Mn_1.25Ga. In the austenitic pha…
Time-dependent density functional theory calculation of van der Waals coefficient of sodium clusters
Arup Banerjee, Aparna Chakrabarti, Tapan K. Ghanty
In this paper we employ all-electron \textit{ab-initio} time-dependent density functional theory based method to calculate the long range dipole-dipole dispersion coefficient (van…
Martensitic transition, ferrimagnetism and Fermi surface nesting in Mn_2NiGa
S. R. Barman, S. Banik, A. K. Shukla +2
The electronic structure of Mn_2NiGa has been studied using density functional theory and photoemission spectroscopy. The lower temperature tetragonal martensitic phase with c/a= 1…
Influence of Ni doping on the electronic structure of Ni_2MnGa
Aparna Chakrabarti, C. Biswas, S. Banik +3
The modifications in the electronic structure of Ni_{2+x}Mn_{1-x}Ga by Ni doping have been studied using full potential linearized augmented plane wave method and ultra-violet phot…
