Microscopic probing of the superconducting and normal state properties of Ta₂V_3.1Si_0.9 by muon spin rotation.

ABSTRACT: The two-dimensional kagome lattice is an experimental playground for novel physical phenomena, from frustrated magnetism and topological matter to chiral charge order and unconventional superconductivity. A newly identified kagome superconductor, Ta₂V_3.1Si_0.9 has recently gained attention for possessing a record high critical temperature, T _C = 7.5 K for kagome metals at ambient pressure. In this study we conducted a series of muon spin rotation measurements to delve deeper into understanding the superconducting and normal state properties of Ta₂V_3.1Si_0.9. We demonstrate that Ta₂V_3.1Si_0.9 is a bulk superconductor with either a s+s-wave or anisotropic s-wave gap symmetry, and
