N2 - Detailed neutron diffraction experiments have been performed on tetragonal R11B2C2 (R = rare-earth) compounds which show characteristic antiferroquadrupolar orderings. TbB2C2, ErB2C2 and HoB2C2, which have magnetic long-periodic states, show anomalous magnetic diffuse scattering with flat intensity. The anomalous diffuse scattering exists in a small region in the reciprocal space, surrounded by satellite peaks, due to the long-periodic magnetic structures. The profile and temperature dependence of the anomalous diffuse scattering indicate that the origin cannot be understood on the basis of magnetic short-range correlations.
