Emergence of spin-phonon coupling in a Gd-doped YCoMnO double perovskite oxide: a combined experimental and ab-initio study
Anasua Khan, Debdatta Banerjee, Divya Rawat +4
We present Raman spectroscopy results backed by first-principles calculations and investigate the nature of possible spin-phonon coupling (SPC) in a Gd-doped YCoMnO (YGCMO)…
Pressure induced emergence of visible luminescence in : Effect of structural distortion in optical behaviour
Debabrata Samanta, Pinku Saha, Bishnupada Ghosh +4
We report emergence of photoluminescence at room temperature in trigonal at high pressures. Enhancement in intensity with pressure is found to be driven by increase…
Lattice dynamics of topological Dirac semimetal LaAgSb with charge density wave ordering
Ratnadwip Singha, Sudeshna Samanta, Tara Shankar Bhattacharya +5
LaAgSb is a rare material, which offers the opportunity to investigate the complex interplay between charge density wave (CDW) ordering and topology protected electronic band…
Water incorporation in Fe-containing wadsleyite from density functional theory at extreme conditions
Tilak Das, Swastika Chatterjee, Tanusri Saha-Dasgupta
Using first-principles density functional theory (DFT), we studied the issue of water incorporation in iron bearing wadsleyite (MgSiO)mineral at transition zone pressures a…
Defect-induced modulation of magnetic, electronic and optical properties of double perovskite oxide LaCoMnO
Anasua Khan, Swastika Chatterjee, T. K. Nath +1
Electron- and hole-doped LaCoMnO(LCMO) are investigated using first principles DFT calculations. Hole and electron doping are achieved respectively by introducing Sr…
Probing lattice dynamics and electron-phonon coupling in topological nodal-line semimetal ZrSiS
Ratnadwip Singha, Sudeshna Samanta, Swastika Chatterjee +6
Topological materials provide an exclusive platform to study the dynamics of relativistic particles in table-top experiments and offer the possibility of wide-scale technological a…
