报告摘要：Since the discovery of topological insulators, Dirac and Weyl semimetals, the study and exploration of topological materials has been a focus in condensed matter physics community. In this talk, the speaker will present their recent results on crystal growth and magnetotransport study of several possible topological semimetal candidates. It is found that possible TRS-breaking Weyl state may be realized in YbMnSb2 and the angle-dependent interlayer magnetoresistance indicates the interlayer transport is coherent. Study on BaZnBi2 indicates that it is possibly a topological trivial semimetal, quite different from Mn-based materials with the same crystal structure, which are usually reported as topological nontrivial semimetal candidates.
