This study focuses on the transport properties of the quasi-kagome compound URhSn, which exhibits successive phase transitions at TC = 16 K (ferromagnetic phase) and TO = 54 K (intermediate phase). A large anomalous Hall component is present along the easy-magnetization axis (H ∥ [0001]), and the Hall resistivity shows a very complex temperature- and field-dependence, with a sign reversal at low temperatures. Below TO, the Hall resistivity exhibits a nonlinear and unusual field-dependence.

Abstract We report single-crystal growth and demonstrate Ising-type ferromagnetism with a Curie temperature of 25 K in UNi4P2 by means of magnetization, electrical transport, and specific heat measurements. Uniaxial anisotropy in magnetism and cf hybridization are well reflected not only in the crystallographic ac plane but also within the basal plane of the tetragonal unit cell owing to the quasi-one-dimensional crystal and electronic structure of UNi4P2.
