摘要: The unfilled skutterudite family has recently gained attention as a potential platform for hosting Dirac states. In this study, we systematically investigate the transport properties of IrSb$_{3}$ single crystals. Magnetoresistance measurements exhibit prominent Shubnikov-de Haas oscillations and negative magnetoresistance at low temperatures. Quantum oscillation analysis extracts a nontrivial Berry phase and confirms a three-dimensional Fermi surface. Additionally, density functional theory calculations indicate the presence of nontrivial topological bands and surface states, suggesting that IrSb$_{3}$ is a topological semimetal. These findings contribute to the growing family of topological materials and provide a platform for further exploration of quantum transport phenomena.
