Magnetic exchange interactions in the molecular orbital spin system NaV2O5 from a distributed moment point of view
Claudio Garcia, Ilteris K. Turan, Swagata Acharya +3
The magnetism in NaV2O5 results from doping of the narrow split-off conduction band of V2O5, which becomes half-filled and leads to a Mott-insulating splitting of spin resolved ban…

Origin of metal-insulator transition in rare-earth Nickelates
Swagata Acharya, Brooks Tellekamp, Jerome Jackson +4
Rare-earth nickelates RNiO3 (R=rare-earth element) exhibit three kinds of phase transitions with decreasing temperature: a structural transition from a pseudo-cubic to a monoclinic…

Electronic structure and magnetism in P4/nmm KCoO2
Ozan Dernek, Santosh Kumar Radha, Jerome Jackson +1
KCoO2 has been found in 1975 to exist in a unique structure with P4/nmm spacegroup with Co in a square pyramidal coordination with the Co atoms in the plane linked by O in a square…
