Interlayer quantum transport in Dirac semimetal BaGa
Sheng Xu, Changhua Bao, Yi-Yan Wang +8
Quantum limit is quite easy to achieve once the band crossing exists exactly at the Fermi level () in topological semimetals. In multilayered Dirac fermion system, the density…

Shubnikov-de Haas and de Haas-van Alphen oscillations in topological semimetal CaAl4
Sheng Xu, Jian-Feng Zhang, Yi-Yan Wang +6
We report the magneto-transport properties of CaAl single crystals with structure at low temperature. CaAl exhibits large unsaturated magnetoresistance 3000$\%…

Unusual magnetotransport in holmium monoantimonide
Yi-Yan Wang, Lin-Lin Sun, Sheng Xu +2
We report the magnetotransport properties of HoSb, a semimetal with antiferromagnetic ground state. HoSb shows extremely large magnetoresistance (XMR) and Shubnikov-de Haas (SdH) o…
