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 (…
Understanding the ferromagnetic insulating state in Cr doped VO
Shishir Kumar Pandey, Abhinav Kumar, Sagar Sarkar +1
Experimentally Cr doping in the rutile phase of VO is found to stabilize a charge ordered ferromagnetic insulating state in the doping range of 10\% to 20\%. In this work, we i…
Anomalous electron transport in epitaxial NdNiO films
Shashank Kumar Ojha, Sujay Ray, Tanmoy Das +8
The origin of simultaneous electronic, structural and magnetic transitions in bulk rare-earth nickelates (NiO) remains puzzling with multiple conflicting reports on the nat…
Strain-induced stripe phase in charge ordered single layer NbSe
Fabrizio Cossu, Krisztián Palotás, Sagar Sarkar +2
Charge density waves are ubiquitous phenomena in metallic transition metal dichalcogenides. In NbSe, a triangular structural modulation is coupled to a charge modula…
The driving force for charge ordering in rare earth nickelates
Basudeb Mandal, Sagar Sarkar, Shishir Kumar Pandey +4
We show that charge ordering (more precisely, two-sublattice bond disproportionation) in the rare earth nickelate perovskites is intimately related to a negative charge transfer en…
Driving force for martensitic transformation in NiMnSn
Soumyadipta Pal, Sagar Sarkar, Shishir Kumar Pandey +2
The martensitic transformation in NiMnSn alloys has been investigated within ab-initio density functional theory. The experimental trend of a martensitic tran…
