High-fi eld moment polarization in the itinerant ferromagnet URhSi
Résumé
We report a high-magnetic-field study of the itinerant ferromagnet URhSi. Magnetization and electrical resistivity were measured under magnetic fields μ 0 H up to 58 T applied along the directions a, b, and c of the orthorhombic structure and temperatures T ranging from 1.5 to 50 K. For H b, pseudo-metamagnetism at μ 0 H m 30-40 T is associated with a broad step in the magnetization and a maximum in the resistivity. The properties of URhSi are discussed and compared with those of the isostructural superconducting ferromagnets URhGe and UCoGe and of the superconducting paramagnet UTe 2 .
