Ab initio Study of Effect of Co Substitution on the Magnetic Properties of Ni and Pt-based Heusler Alloys
Tufan Roy, Aparna Chakrabarti
Using density functional theory based calculations, we have carried out in-depth studies of effect of Co substitution on the magnetic properties of Ni and Pt-based shape memory all…
High pressure studies on properties of FeGa3: role of on-site coulomb correlation
Debashis Mondal, Velaga Srihari, C. Kamal +7
High pressure X-ray diffraction measurements have been carried out on the intermetallic semiconductor FeGa and the equation of state for FeGa has been determined. First pri…
Structural and electronic properties of Fe(AlxGa1-x)3 system
Debashis Mondal, C. Kamal, Soma Banik +6
FeGa3 is a well known d-p hybridization induced intermetallic bandgap semiconductor. In this work, we present the experimental and theoretical results on the effect of Al substitut…
Electronic Structure of FeAl Alloy Studied by Resonant Photoemission Spectroscopy and Ab Initio Calculations
Debashis Mondal, Soma Banik, C. Kamal +7
Resonant photoemission spectroscopy has been used to investigate the character of Fe 3d states in FeAl alloy. Fe 3d states have two different character, first is of itinerant natur…
Magnetic Interactions and Electronic Structure of PtMnYGa (Y = Cr and Fe) system : An ab-initio calculation
Tufan Roy, Aparna Chakrabarti
First principles density functional theory based calculations have been carried out to predict the effects of Mn replacement by Fe and Cr on electronic as well as magnetic properti…
Probing the possibility of coexistence of martensite transition and half-metallicity in Ni and Co-based full Heusler Alloys : An ab initio Calculation
Tufan Roy, Dhanshree Pandey, Aparna Chakrabarti
