Abstract
Neutron diffraction studies were performed on the compounds ErB4 and DyB4 at 4.2 and 300 K. Both compounds are antiferromagnetically ordered at 4.2 K. A determination of the magnetic structure type is given for ErB4 and DyB4. The magnetic intensities were studied as a function of temperature, leading to Néel temperatures TN=16.3 K (ErB4) and TN=21 K (DyB4). The relative stability of several simple magnetic structures, appropriate to RB4, are discussed in terms of the RKKY model, together with previously reported results of magnetization and NMR studies on these compounds.Keywords
