    NdRhSn has a ferromagnetic ground state [Tt = 7.6(1) K] with a magnetic moment equal to 2/3 of the free Nd3+-ion moment. Upon cooling from the paramagnetic state, the ferromagnetism is preceded by an incommensurate antiferromagnetic state between TN = 9.8(1) K and Tt. In both magnetic phases the magnetic moments are locked along the c axis,which is the easy-magnetization axis of the system.We have investigated this unusual situation bymeasuring anomalies of several bulk physical properties characteristic for the magnetic phase transitions at TN and Tt and the response of these properties to an applied magnetic field. Neutron-diffraction experiments have been also performed at lowtemperatures. In order to understand better the physical properties of NdRhSn, single crystals have been studied under external hydrostatic and uniaxial pressure and in high magnetic fields.
