Tetramer Orbital-Ordering induced Lattice-Chirality in Ferrimagnetic, Polar MnTi2O4
A. Rahaman, M. Chakraborty, T. Paramanik +6
Using density-functional theory calculations and experimental investigations on structural, magnetic and dielectric properties, we have elucidated a unique tetragonal ground state…
Magnetic interactions at the nanoscale in trilayer titanates LaTiO/SrTiO/YTiO
Yanwei Cao, Zhenzhong Yang, M. Kareev +10
We report on the phase diagram of competing magnetic interactions at nanoscale in engineered ultra-thin trilayer heterostructures of LaTiO/SrTiO/YTiO, in which th…
Metallic interface in non-SrTiO3 based titanate superlattice
Xiaoran Liu, D. Choudhury, Yanwei Cao +3
We report on the fabrication of all perovskite Mott insulator/band insulator YTiO3/CaTiO3 superlattices by pulsed laser deposition. The combination of in situ reflection high energ…
Anomalous charge and negative-charge-transfer insulating state in cuprate chain-compound KCuO_2
D. Choudhury, P. Rivero, D. Meyers +8
Using a combination of X-ray absorption spectroscopy experiments with first principle calculations, we demonstrate that insulating KCuO_2 contains Cu in an unusually-high formal-3+…
Engineered Mott ground state in LaTiO/LaNiO heterostructure
Yanwei Cao, Xiaoran Liu, M. Kareev +7
In pursuit of creating cuprate-like electronic and orbital structures, artificial heterostructures based on LaNiO have inspired a wealth of exciting experimental and theoretica…
Epitaxial Growth of (1 1 1)-Oriented Spinel CoCrO/AlO Heterostructures
Xiaoran Liu, D. Choudhury, Yanwei Cao +6
High quality (1 1 1)-oriented CoCrO/AlO heterostructures were synthesized on the sapphire (0 0 0 1) single crystal substrates in a layer-by-layer mode. The structur…
