Studies on the monosulfides and nitrides of U and Th reveaied that US is ferromagnetic with a Curie point at 180 deg K and a molar susceptibility of 6280 x 10/sup -6/ emu at 298 deg K ( mu /sup BETA / = 2.46), while ThS and ThN are diamagnetic. The phase UN/sub 1.33/ (U/sub 3/N/sub 4/) was found to be antiferromagnetic with a Weiss constant theta = -262, but the phases with lower nitrogen content behave in a manner characteristic of ferrimagnetic materials. The ferrimagnetic behavior of lower nltrides may be best explained by the presence of a sublattice of U/sup 3+/, which would tend to form and grow as the nitrogen content is decreased. The monosulfide and mononitride of Th are electronic conductors with a low specific resistivity ( approximates 10/sup -4/ ohm-cm) and a Seebeck coefficient of a few mu volts per degree at room temperature. Between room temperature and 1300 deg K the resistivity for the uranium compounds increases very slightly: from 0.9 to 1.4 x 10/sup -4/ ohm-cm for UN and from 3.6to 4.3 x 10/sup -4/ ohm-cm for US.
