Momentum-Resolved Fingerprint of Mottness in Layer-Dimerized NbBr
Mihir Date, Francesco Petocchi, Yun Yen +20
In a well-ordered crystalline solid, insulating behaviour can arise from two mechanisms: electrons can either scatter off a periodic potential, thus forming band gaps that can lead…
Quantum spin liquids by geometric lattice design
Xiaoran Liu, T. Asaba, Qinghua Zhang +12
On a lattice composed of triangular plaquettes where antiferromagnetic exchange interactions between localized spins cannot be simultaneously satisfied, the system becomes geometri…
Emergent magnetic state in (111)-oriented quasi-two-dimensional spinel oxides
Xiaoran Liu, B. J. Kirby, Zhicheng Zhong +8
We report on the emergent magnetic state of (111)-oriented CoCr2O4 ultrathin films sandwiched by Al2O3 in the quantum confined geometry. At the two-dimensional crossover, polarized…
Interface-engineered hole doping in Sr2IrO4/LaNiO3 heterostructure
Fangdi Wen, Xiaoran Liu, Qinghua Zhang +9
The relativistic Mott insulator Sr2IrO4 driven by large spin-orbit interaction is known for the Jeff = 1/2 antiferromagnetic state which closely resembles the electronic structure…
Doping induced site-selective Mott insulating phase in LaFeO
S. Jana, S. K. Panda, D. Phuyal +17
Tailoring transport properties of strongly correlated electron systems in a controlled fashion counts among the dreams of materials scientists. In copper oxides, varying the carrie…
Evolution of ferromagnetism in two-dimensional electron gas of LaTiO3/SrTiO3
Fangdi Wen, Yanwei Cao, Xiaoran Liu +4
Understanding, creating, and manipulating spin polarization of two-dimensional electron gases at complex oxide interfaces presents an experimental challenge. For example, despite a…
