Epitaxial stabilization of ultra thin films of high entropy perovskite
Ranjan Kumar Patel, Shashank Kumar Ojha, Siddharth Kumar +4
High entropy oxides (HEOs) are a class of materials, containing equimolar portions of five or more transition metal and/or rare-earth elements. We report here about the layer-by-la…
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…
Conductivity noise across temperature driven transitions of rare-earth nickelate heterostructures
Gopi Nath Daptary, Siddharth Kumar, M. Kareev +3
The metal-insulator transition (MIT) of bulk rare-earth nickelates is accompanied by a simultaneous charge ordering (CO) transition. We have investigated low-frequency resistance f…
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…
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…
