| 英文摘要 | The magnetic semimetal SrMnSb2 contains a nonsymmorphic crystal symmetry that could protect Dirac crossings, offering the coexistence of a quasi-two-dimensional characteristic, magnetic order and nontrivial topology in bulk single crystals. Here, we report the evolution of Fermi surfaces by probing quantum oscillations in the LaxSr1-xMnSb2 single crystals. Hall measurements reveal that the conduction process changes from a hole-dominated multiband nature to a single hole-band nature after La doping. Compared with parent-SrMnSb2, the Fermi surface corresponding to F-alpha is slightly enlarged and the small Fermi surface corresponding to F-gamma appears with a tunable feature in La-doped crystals. The topological semimetal candidates LaxSr1-xMnSb2 provide a fine-tuning platform for potential applications in the future. |
