A single crystal of U2NiSi3 was investigated by means of magnetization, electrical resistivity and heat capacity measurements. Whereas the DC magnetic data clearly manifest strongly anisotropic ferromagnetism, the AC magnetic susceptibility data are consistent with spin-glass behaviour, reported previously for polycrystalline samples. Moreover, no distinct anomalies around TC occur in the specific heat and electrical resistivity characteristics. Altogether the results obtained for single-crystalline U2NiSi3 indicate rather an unusual state of coexistence of ferromagnetism and spin-glass freezing.
