摘要
The magnetic properties of polycrystalline samples of PrCuSn and NdCuSn, including their magnetic structures, were determined by magnetic and neutron diffraction measurements. Both compounds show the hexagonal, CaIn2-type crystal structure and are antiferromagnetic at low temperatures. Below T-N = 3 K, the sine modulated magnetic structure with the wave vector k = (0.349, 0, 0) is observed in PrCuSn, while in NdCuSn below T-N = 9 K the collinear antiferromagnetic ordering described by the wave vector k = (1/2, 0, 0) was detected. In both phases the magnetic moments are parallel to the hexagonal c-axis.
