Utilizing muon spin rotation/relaxation (µSR) measurements on independently grown UTe₂ single crystals, this study reveals the presence of magnetic clusters that undergo freezing into a disordered state at low temperatures. This magnetic inhomogeneity is linked to the linear term in the specific heat and its low-temperature upturn, potentially impacting the determination of UTe₂'s intrinsic properties.
