Low temperature magnetism in the perovskite substrate DyScO_>

We investigate the low temperature magnetic properties of crystalline DyScO3, a material that has seen increasing importance as a substrate for the growth of strained perovskite films. The compound exhibits strong magnetic anisotropy with an easy axis along the [100] direction and a hard axis along the [001] direction, respectively, attributable to magnetocrystalline anisotropy. We find that DyScO3 undergoes a magnetic phase transition at 3.1 K, presumably from paramagnetism to antiferromagnetic long range order. The presence of such a transition and the magnetic anisotropy suggests the possibility of significant substrate impact on studies of the magnetism of the epitaxial thin films grown on this material.
