Room-Temperature Valence Transition in a Strain-Tuned Perovskite Oxide
Vipul Chaturvedi, Supriya Ghosh, Dominique Gautreau +17
Cobalt oxides have long been understood to display intriguing phenomena known as spin-state crossovers, where the cobalt ion spin changes vs. temperature, pressure, etc. A very dif…
Room-temperature ferromagnetism at an oxide/nitride interface
Qiao Jin, Zhiwen Wang, Qinghua Zhang +26
Heterointerfaces have led to the discovery of novel electronic and magnetic states because of their strongly entangled electronic degrees of freedom. Single-phase chromium compound…
Atomic structure of initial nucleation layer in hexagonal perovskite BaRuO thin films
Sangmoon Yoon, Jong Mok Ok, Sang A Lee +4
Hexagonal perovskites are an attractive group of materials due to their various polymorph phases and rich structure-property relationships. BaRuO3 (BRO) is a prototypical hexagonal…
Flat Band Induced Negative Magnetoresistance in Multi-Orbital Kagome Metal
Jie Zhang, T. Yilmaz, J. W. R. Meier +14
Electronic flat band systems are a fertile platform to host correlation-induced quantum phenomena such as unconventional superconductivity, magnetism and topological orders. While…
Twin-domain formation in epitaxial triangular lattice delafossites
Jong Mok Ok, Sangmoon Yoon, Andrew R. Lupini +4
Twin domains are often found as structural defects in symmetry mismatched epitaxial thin films. The delafossite ABO2, which has a rhombohedral structure, is a good example that oft…
Dimensional Control of Octahedral Tilt in SrRuO3 via Infinite-layered Oxides
Shan Lin, Qinghua Zhang, Xiahan Sang +16
Manipulation of octahedral distortion at atomic length scale is an effective means to tune the physical ground states of functional oxides. Previous work demonstrates that epitaxia…
