Extremely large magnetoresistance in a topological semimetal candidate pyrite PtBi2
Wenshuai Gao, Ningning Hao, Fa-Wei Zheng +12
While pyrite-type PtBi2 with face-centered cubic structure has been predicted to be a three-dimensional (3D) Dirac semimetal, experimental study on its physical properties remains…
Transport evidence for the three-dimensional Dirac semimetal phase in ZrTe5
Guolin Zheng, Jianwei Lu, Xiangde Zhu +10
Topological Dirac semimetal is a newly discovered class of materials and has attracted intense attentions. This material can be viewed as a three-dimensional (3D) analogue of graph…
1T`-MoTe2 single crystal: a possible topological superconductor
X. Luo, F. C. Chen, J. L. Zhang +7
We measured the magnetoresistvity (MR) properties of the 1T`-MoTe2 single crystal under the magnetic field up to 33 T.By analyzing the Shubnikov de Haas oscillations of MR at the l…
Nature of charge density waves and superconductivity in 1\emph{T}-TaSeTe
Y. Liu, D. F. Shao, L. J. Li +13
Transition-metal dichalcogenides (TMDs) ( = Ti, Nb, Ta; = S, Se, Te) exhibit a rich set of charge density wave (CDW) orders, which usually coexist and/or compete with…
Field-induced resistivity plateau and unsaturated negative magnetoresistance in topological semimetal TaSb2
Yuke Li, Lin Li, Jialu Wang +5
Several prominent transport properties have been identified as key signatures of topologicalmaterials. One is the resistivity plateau at low temperatures as observed in several top…
Signature of chiral fermion instability in the Weyl semimetal TaAs above the quantum limit
Cheng-Long Zhang, Bingbing Tong, Zhujun Yuan +7
We report the electrical transport properties for Weyl semimetal TaAs in an intense magnetic field. Series of anomalies occur in the longitudinal magnetoresistance and Hall signals…
