Single crystals of paramagnetic semiconductor β-US2 with the orthorhombic (Pnma) crystal structure were grown by chemical transport method. We measured the electrical resistivity ρ under high pressure, and magnetization. With increasing pressure, the temperature dependence of ρ approaches to semimetallic behavior and a kink anomaly appears at Ta. Ta shifts to higher temperature with increasing pressure. From the comparison with ferromagnetic semimetal UTeS having the same crystal structure, it seems that Ta is a ferromagnetic transition.
