Flux-flow instability across Berezinskii Kosterlitz Thouless phase transition in KTaO (111) based superconductor
Shashank Kumar Ojha, Prithwijit Mandal, Siddharth Kumar +2
The nature of energy dissipation in 2D superconductors under perpendicular magnetic field at small current excitations has been extensively studied over the past two decades. Howev…
Hole doping in a negative charge transfer insulator
Ranjan Kumar Patel, Krishnendu Patra, Shashank Kumar Ojha +7
NiO is a negative charge transfer energy system and exhibits a temperature-driven metal-insulator transition (MIT), which is also accompanied by a bond disproportionation (…
Electronic and magnetic properties of epitaxial thin film of Nd\tsubscript{0.5}Ba\tsuscriptb{0.5}MnO\tsubscript{3}
Siddharth Kumar, Shashank Kumar Ojha, Ranjan Kumar Patel +3
Contradictory reports about the electronic and magnetic behavior of bulk Nd0:5Ba0:5MnO3 with uniform disorder exist in the literature. In this work, we investigate the thin films o…
