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 phase in short-periodic rare-earth nickelate superlattices
S. Middey, Ranjan Kumar Patel, D. Meyers +6
Heterostructure engineering provides an efficient way to obtain several unconventional phases of LaNiO3, which is otherwise paramagnetic, metallic in bulk form. In this work, a new…
Stabilization of high-pressure GeCuO spinel cuprate with quasi-1D chains in the epitaxial thin-film form
Denis M. Vasiukov, Mikhail Kareev, Fangdi Wen +3
GeCuO is a high-pressure recoverable cuprate with a strongly tetragonally elongated spinel structure and magnetic lattice formed by CuO linear chains with frust…
Unconventional crystal field splitting in non-centrosymmetric BaTiO thin films
Yang Song, Xiaoran Liu, Fangdi Wen +10
Understanding the crystal field splitting and orbital polarization in non-centrosymmetric systems such as ferroelectric materials is fundamentally important. In this study, taking…
Epitaxial stabilization of thin films of the frustrated Ge-based spinels
Denis M. Vasiukov, Mikhail Kareev, Fangdi Wen +5
Frustrated magnets can host numerous exotic many-body quantum and topological phenomena. GeNiO is a three dimensional frustrated magnet with an unusual two-stage tran…
Berry phase manipulation in ultrathin SrRuO films
Liang Wu, Fangdi Wen, Yixing Fu +7
A notion of the Berry phase is a powerful means to unravel the non-trivial role of topology in various novel phenomena observed in chiral magnetic materials and structures. A celeb…
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…
Nucleation and growth bottleneck in the conductivity recovery dynamics of nickelate thin films
Elsa Abreu, Derek Meyers, Verner K. Thorsmolle +5
We investigate THz conductivity dynamics in NdNiO and EuNiO thin films following a photoinduced thermal quench into the metallic state and reveal a clear contrast between f…
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…
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…
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…
