Detailed {sup 119}Sn M{umlt o}ssbauer studies were performed on the ferromagnetic uranium intermetallic compounds UTSn (T=Co, Rh, Ir, Ru) both above and below their Curie temperatures. The analysis of the experimental results allowed to determine the direction of magnetization which coincides with the crystallographic c axis for all these compounds as well as to define the orientations of the principal axes of the electric field gradient tensor with respect to the crystallographic axes. For UCoSn, URhSn, and UIrSn, the V{sub yy} component is parallel to the c axis while in the case of URuSn, the V{sub zz} component is parallel to this axis. The M{umlt o}ssbauer spectra taken at higher temperatures demonstrate a considerable distribution of magnitudes of the transferred magnetic hyperfine fields as well as a coexistence of magnetic and nonmagnetic contributions close to the Curie temperatures. {copyright} {ital 1997} {ital The American Physical Society}
