Dichotomy of flat bands in the van der Waals ferromagnet FeGeTe
Han Wu, Jianwei Huang, Chaowei Hu +28
Quantum materials with bands of narrow bandwidth near the Fermi level represent a promising platform for exploring a diverse range of fascinating physical phenomena, as the high de…
Reversible Non-Volatile Electronic Switching in a Near Room Temperature van der Waals Ferromagnet
Han Wu, Lei Chen, Paul Malinowski +37
The ability to reversibly toggle between two distinct states in a non-volatile method is important for information storage applications. Such devices have been realized for phase-c…
Spin structure and dynamics of the topological semimetal CoSnInS
Kelly J. Neubauer, Feng Ye, Yue Shi +7
The anomalous Hall effect (AHE), typically observed in ferromagnetic (FM) metals with broken time-reversal symmetry, depends on electronic and magnetic properties. In CoSn$_{…
Evidence for equilibrium excitons and exciton condensation in monolayer WTe2
Bosong Sun, Wenjin Zhao, Tauno Palomaki +14
A single monolayer of the layered semimetal WTe2 behaves as a two-dimensional topological insulator, with helical conducting edge modes surrounding a bulk state that becomes insula…
Apparatus Design for Measuring of the Strain Dependence of the Seebeck Coefficient of Single Crystals
Tiema Qian, Joshua Mutch, Lihua Wu +3
We present the design and construction of an apparatus that measures the Seebeck coefficient of single crystals under in-situ tunable strain at cryogenic temperatures. A home-built…
The transport-structural correspondence across the nematic phase transition probed by elasto-x-ray diffraction
Joshua J Sanchez, Paul Malinowski, Joshua Mutch +4
Electronic nematicity in iron pnictide materials is coupled to both the lattice and the conducting electrons, which allows both structural and transport observables to probe nemati…
