Band Structure of Topological Insulator BiSbTe1.25Se1.75
H. Lohani, P. Mishra, A. Banerjee +6
We present our angle resolved photoelectron spectroscopy (ARPES) and density functional theory results on quaternary topological insulator (TI) BiSbTe1.25Se1.75 (BSTS) confirming t…
Site-substitution in GdMnO3 : effects on structural, electronic and magnetic properties
Sudipta Mahana, Bipul Rakshit, Pronoy Nandi +5
We report on detailed structural, electronic and magnetic studies of GdMnCrO for Cr doping levels 0 1. In the solid solutions, the Jahn-Teller disto…
Role of local structural distortion in driving ferroelectricity in GdCrO3
Sudipta Mahana, U. Manju, Pronoy Nandi +3
Temperature dependent synchrotron x-ray diffraction and extended x-ray absorption fine structure (EXAFS) studies were performed to understand the role of structural characteristics…
Local inversion symmetry breaking and spin-phonon coupling in perovskite GdCrO3
Sudipta Mahana, Bipul Rakshit, Raktima Basu +5
Our detailed temperature dependent synchrotron powder x-ray diffraction studies along with first-principles density functional perturbation theory calculations, enable us to shed l…
Structural and electronic phase evolution of Tin dioxide
Sudipta Mahana, Pitamber Sapkota, Saptarshi Ghosh +2
We investigate the effect of controlled annealing on the structural and electronic phase evolution of Tin dioxide from Tin (II) oxyhydroxide prepared by simple precipitation method…
Magnetic Proximity Effect as a Pathway to Spintronic Applications of Topological Insulators
Ivana Vobornik, Unnikrishnan Manju, Jun Fujii +6
Spin-based electronics in topological insulators (TIs) is favored by the long spin coherence1,2 and consequently fault-tolerant information storage. Magnetically doped TIs are ferr…
