Phase transition and anomalous scaling in the quantum Hall transport of topological insulator Sn-Bi1.1Sb0.9Te2S devices
Faji Xie, Shuai Zhang, Qianqian Liu +12
The scaling physics of quantum Hall transport in optimized topological insulators with a plateau precision of ~1/1000 e2/h is considered. Two exponential scaling regimes are observ…
Novel magnetic field tuning of quantum spin excitations in a weakly coupled 1/2 Heisenberg spin chain as seen from NMR
Long Ma, Z. Wang, L. Hu +3
We report our NMR study of the spin excitations in the quasi-one dimensional (1D) quantum magnet CHNHCu(HCOO) lying in the 1D-3D dimensional crossover regime wi…
Origin of planar Hall effect in type-II Weyl semimetal MoTe2
D. D. Liang, Y. J. Wang, W. L. Zhen +8
Besides the negative longitudinal magnetoresistance (MR), planar Hall effect (PHE) is a newly emerging experimental tool to test the chiral anomaly or nontrivial Berry curvature in…
Current jetting distorted planar Hall effect in a Weyl semimetal with ultrahigh mobility
J. Yang, W. L. Zhen, D. D. Liang +8
A giant planar Hall effect (PHE) and anisotropic magnetoresistance (AMR) is observed in TaP, a nonmagnetic Weyl semimetal with ultrahigh mobility. The perpendicular resistivity (i.…
Extreme magnetoresistance and Shubnikov-de Haas oscillations in ferromagnetic DySb
D. D. Liang, Y. J. Wang, C. Y. Xi +5
The electronic structures of a representative rare earth monopnictide (i.e., DySb) under high magnetic field (i.e., in the ferromagnetic state) are studied from both experimental a…
Frustration induced non-Curie-Weiss paramagnetism in La3Ir3O11: a fractional-valence-state iridate
J. Yang, J. R. Wang, W. L. Zhen +6
Experimental and theoretical studies are performed on La3Ir3O11, an iridate hosting a +4.33 fractional valence state for Ir ions and a three-dimensional frustrated structure compos…
