Dirac cone in a non-honeycomb surface alloy
Pampa Sadhukhan, Dhanshree Pandey, Vipin Kumar Singh +5
We demonstrate unexpected occurrence of linear bands resembling Dirac cone at the zone-center of AuSn surface alloy with $\left( \begin{smallmatrix} 2&1\\ 1&3 \end{smallmatrix}…
Influence of anti-site disorder and electron-electron correlations on the electronic structure of CeMnNi
Pampa Sadhukhan, Sunil Wilfred D'Souza, Vipin Kumar Singh +7
CeMnNi exhibits an unusually large spin polarization, but its origin has baffled researchers for more than a decade. We use bulk sensitive hard x-ray photoelectron spectroscopy…
Enhancement of the density of states at the Fermi level due to oxygen atoms in noble metals
Sudipta Roy Barman, Aparna Chakrabarti
The interaction of oxygen with noble metals such as silver has been an important topic of research for many decades. Here, we show occurrence of a peak in the density of states (DO…
Presence of atomic disorder and its effect on magnetic and electronic properties of NiCrGa half Heusler alloy
Madhusmita Baral, M. K. Chattopadhyay, Aparna Chakrabarti +1
In this work, polycrystalline NiCrGa half Heusler alloy, which is predicted to be half-metallic ferromagnet from first principles calculations, has been synthesized by arc meting t…
An experimental and Ab-initio study of Electronic and Magnetic properties of FeGa3
Debashis Mondal, Soma Banik, C. Kamal +5
Electronic structure of FeGa3 has been studied using experiments and ab-initio calculations. Magnetization measurements show that FeGa3 is inherently diamagnetic in nature. Our stu…
