Description
Summary:Abstract Superconducting topological materials have generated considerable interest in condensed matter research due to their unusual gap structures and topological properties. In this study, the normal and superconducting characteristics of a potential topological semimetal, 1 T ‐NbSeTe are investigated through comprehensive transport and magnetization measurements on bulk single crystals. The results suggest the topological semimetallic nature of NbSeTe, as evidenced by the observation of the planar Hall effect. Moreover, it displays quasi‐2D anisotropic superconductivity, which breaks the Pauli limit. The coexistence of the topological semimetallic nature and superconductivity of NbSeTe makes it a potential contender for topological superconductivity.
