A NdRhSn single crystal has been grown and investigated with respect to crystal structure and magnetic behavior. The magnetization and specific heat were measured as functions of temperature and the magnetic field applied along the crystallographic a- and c-axis, respectively. A strong uniaxial magnetocrystalline anisotropy with the c-axis as the easy magnetization direction has been observed. The obtained experimental data can be conceived within the following scenario of magnetism in NdRhSn: the paramagnetic-antiferromagnetic phase transition at 9.8K and at 7.6 K, an order-to-order magnetic phase transition takes place. The magnetic state below 7.6K is characterized by a spontaneous magnetization corresponding to similar to 2/3 of the value of the Nd3+ free-ion moment. This may be either due to crystal-field effects or due to a complex ground-state magnetic structure.
