Superconductivity and electron correlations in the kagome metal LuOs 3 B 2

Year: 2025

Type: article

Abstract: The authors report superconductivity at ${T}_{c}$~4.63 K in the ideal kagome lattice LuOs${}_{3}$B${}_{2}$. Combined resistivity, magnetization, and specific heat measurements confirm a moderately coupled superconducting state, while enhanced Wilson ratios suggest electron correlations. First-principles calculations reveal the nontrivial topological features, with spin-orbit coupling opening gaps at Dirac points. This work paves the way for exploring superconductivity, electronic correlations, and topological states in this compound.
