Abstract
The magnetic structure of DyAsO4 has been determined by neutron diffraction on a powdered sample. DyAsO4 undergoes a transition to a non-collinear antiferromagnetically ordered state at 2.5 K, with an inclination of the magnetic moments of phi b=22 degrees relative to the b axis in the ab plane. The magnetic space group is PI212121 (orthorhombic symmetry). The magnetic moment is 8.6 mu B at 2.2 K. The temperature behaviour of the magnetization is in agreement with an Ising magnet. The crystallographic parameters are determined and possible crystallographic phase transitions are discussed.Keywords
