Abstract:
We grew single crystals of NdRhIn5, TbRhIn5, DyRhIn5, and HoRhIn5 with the tetragonal crystal structure and measured the magnetic susceptibility and magnetization. NdRhIn5 is an antiferromagnet with a Neel temperature T-N = 11.6 K. Below T-N, magnetization reveals two metamagnetic transitions at H-ml = 70 kOe and H-m2 = 93 kOe for the magnetic field along the [001] direction. The saturation moment of 2.5 mu(B)/Nd is in good agreement with the staggered Nd moment determined by the neutron diffraction experiment. These metamagnetic transitions correspond to the change of the magnetic structure. TbRhIn5, DyRhIn5 and HoRhIn5 are found to be antiferromagnets with T-N = 47.3, 28.1, and 15.8 K, respectively. The magnetization curves of these compounds are also quite similar to those of NdRhIn5, revealing two metamagnetic transitions. The magnetic structures in magnetic fields are proposed by considering the exchange interactions based on the crystal structure.
