Neutron powder diffraction study of the magnetic structure of EuZrO3

Neutron powder diffraction experiments on the orthorhombic perovskite EuZrO₃ show it to have an antiferromagnetic G-type magnetic structure with the magnetic moments aligned parallel to the a-axis. The orthorhombic crystal structure is a consequence of cooperative rotations of the corner-sharing ZrO₆ octahedra. The crystal structure does not change significantly below the Néel temperature, ∼4.1 K, showing there to be only weak magnetoelastic coupling.
