Antiferromagnetic order and magnetic polarons in lightly doped LiCoO (x 0.9)
Sudip Pal, Pampa Sadhukhan, Waqar Suleman +2
We investigate the magnetic properties of LiCoO (x0.9) using bulk magnetization, specific heat, nuclear magnetic resonance (NMR) and electron paramagnetic resonance (…
Kramers nodal line in the charge density wave state of YTe and the influence of twin domains
Shuvam Sarkar, Joydipto Bhattacharya, Pramod Bhakuni +13
Recent studies have focused on the relationship between charge density wave (CDW) collective electronic ground states and nontrivial topological states. Using angle-resolved photoe…
Bulk Electronic Structure of Ni2MnGa studied by Density Functional Theory and Hard X-ray Photoelectron Spectroscopy
Joydipto Bhattacharya, Pampa Sadhukhan, Shuvam Sarkar +4
A combined study employing density functional theory (DFT) using the experimentally determined modulated structures and bulk-sensitive hard x-ray photoelectron spectroscopy on sing…
Charge density wave induced nodal lines in LaTe
Shuvam Sarkar, Joydipto Bhattacharya, Pampa Sadhukhan +11
LaTe is a noncentrosymmetric (NC) material with time reversal (TR) symmetry in which the charge density wave (CDW) is hosted by the Te bilayers. Here, we show that LaTe hos…
Electronic structure of Au-Sn compounds grown on Au(111)
Pampa Sadhukhan, Sajal Barman, Tufan Roy +4
The electronic structure of Au-Sn intermetallic layers of different compositions grown on Au(111) to the thickness of several nanometers has been studied in this work. The layer, i…
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…
Quasiperiodic ordering in thick Sn layer on -Al-Pd-Mn: A possible quasicrystalline clathrate
Vipin Kumar Singh, Marek Mihalkovic, Marian Krajčí +9
Realization of an elemental solid-state quasicrystal has remained a distant dream so far in spite of extensive work in this direction for almost two decades. Here, we report the di…
