Abstract

The ferromagnet UTeS with the Curie temperature T_C = 87K has been studied by measuring the magnetization, magnetic susceptibility, electrical resistivity, magnetoresistance, Hall resistivity and specific heat. The magnetization was found to be highly anisotropic. The easy-axis was determined as the [001] direction, whereas the hard-axis magnetization for H ∥ [100] decreases below T_C, indicating an antiferromagnetic feature. The electrical resistivity also indicates a peak structure at T_C. These results suggest that UTeS is a canted ferromagnet. A large negative magnetoresistance was also observed around T_C. From the result of the Hall resistivity measurement, UTeS is thought to be a semimetal. This is consistent with the large value of the electrical resistivity and the small electronic specific heat coefficient.
