We succeeded in growing single crystals of RRhIn5 (R: rare earth) and measured the magnetic susceptibility and magnetization. The lattice constants of RRhIn5 with the tetragonal structure are well understood from a viewpoint of the lanthanide contraction, except YbRhIn5 with the divalent Yb ion. Most of RRhIn5 compounds order antiferromagnetically. NdRhIn5 indicates two metamagnetic transitions at Hm1=7.2 and Hm2=9.6T below TN for the magnetic field along the [001] direction. The saturation moment of 2.5μB/Nd is in good agreement with a staggered Nd moment determined by the neutron scattering experiment. The similar metamagnetic transitions were observed in TbRhIn5, DyRhIn5 and HoRhIn5.
