Lattice and magnetic dynamics in YVO Mott insulator studied by neutron scattering and first-principles calculations
Yu Tao, Douglas L. Abernathy, Tianran Chen +5
The Mott insulator YVO with = 118 K is revisited to explore the role of spin, lattice and orbital correlations across the multiple structural and magnetic transitions…
The elusive quantum anomalous Hall effect in MnBi2Te4: a materials perspective
Jiaqiang Yan
Observation of the quantum anomalous Hall effect (QAHE) in MnBiTe flakes is one of the most exciting results in the study of the intrinsic magnetic topological insulator Mn…
Tuning the Room Temperature Ferromagnetism in Fe5GeTe2 by Arsenic Substitution
Andrew F. May, Jiaqiang Yan, Raphael Hermann +2
In order to tune the magnetic properties of the cleavable high-Curie temperature ferromagnet FeGeTe, the effect of increasing the electron count through arsenic substit…
Electric control of a canted-antiferromagnetic Chern insulator
Jiaqi Cai, Dmitry Ovchinnikov, Zaiyao Fei +11
The interplay between band topology and magnetism can give rise to exotic states of matter. For example, magnetically doped topological insulators can realize a Chern insulator tha…
Atomic-scale analysis of disorder by similarity learning from tunneling spectroscopy
Petro Maksymovych, Jiaqiang Yan, Brian Sales +1
Rapid proliferation of hyperspectral imaging in scanning probe microscopies creates unique opportunities to systematically capture and categorize higher dimensional datasets, towar…
Magnetostriction of α-RuCl3 flakes in the zigzag phase
Yun-Yi Pai, Claire E. Marvinney, Matthew A. Feldman +7
Motivated by the possibility of an intermediate U(1) quantum spin liquid phase in out-of-plane magnetic fields and enhanced magnetic fluctuations in exfoliated α-RuCl3 flakes, we s…
