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 (…
Spin liquid behavior of a three-dimensional magnetic system BaNiIrO with = 1
Siddharth Kumar, S. K. Panda, Manju Mishra Patidar +7
The quantum spin liquid (QSL) is an exotic phase of magnetic materials where the spins continue to fluctuate without any symmetry breaking down to zero temperature. Among the handf…
Epitaxial stabilization of ultra thin films of high entropy perovskite
Ranjan Kumar Patel, Shashank Kumar Ojha, Siddharth Kumar +4
High entropy oxides (HEOs) are a class of materials, containing equimolar portions of five or more transition metal and/or rare-earth elements. We report here about the layer-by-la…
Conductivity noise across temperature driven transitions of rare-earth nickelate heterostructures
Gopi Nath Daptary, Siddharth Kumar, M. Kareev +3
The metal-insulator transition (MIT) of bulk rare-earth nickelates is accompanied by a simultaneous charge ordering (CO) transition. We have investigated low-frequency resistance f…
Electronic structure of a graphene-like artificial crystal of
Arian Arab, Xiaoran Liu, O. Köksal +14
Artificial complex-oxide heterostructures containing ultrathin buried layers grown along the pseudocubic [111] direction have been predicted to host a plethora of exotic quantum st…
