Magnetic structure of URhSi single crystal

Abstract A single crystal of URhSi has been grown and subsequently investigated by magnetization and neutron-diffraction measurements. The neutron-diffraction experiment confirms that URhSi crystallizes in the orthorhombic TiNiSi-type of structure. Low-temperature experimental data point to ferromagnetic order in URhSi below 10.5 K. Similar to previous powder neutron-diffraction experiments, our single-crystal data are consistent with a collinear ferromagnetic ordering of U moments of 0.58±0.09 μ B /U oriented along the crystallographic c -axis. No superconductivity has been detected at temperatures down to 40 mK.
