The ferromagnetic behavior of URhSi (TiNiSi-type orthorhombic crystal structure) resembles its isostructural analogue URhGe, the well-known "ferromagnetic superconductor". We report on first results of magnetization measurements of a URhSi single crystal with respect to a magnetic field and temperature. The magnetization data and specific-heat behavior point to a Curie temperature Tc = 10.5 K. At lower temperatures we observe a strong magnetic anisotropy with the dominant spontaneous magnetic moment (0.47μB) along the c-axis (similar to URhGe). Along the a- and b-axis, much smaller components are indicated. A strong anisotropy is observed also in paramagnetic range.
