Abstract
Polar magnetic oxides are interesting systems to study due to the possibility of hosting functional properties such as ferroelectricity, piezoelectricity etc. In this work, a new compound HoCrWO6 is synthesized using high temperature solid state reaction and characterized using x-ray diffraction, neutron diffraction, magnetization measurements and dielectric measurements. The x-ray and neutron diffraction results indicate that HoCrWO6 crystallizes in polar (non-centrosymmetric and achiral) orthorhombic structure P n a 21. The magnetization measurements indicate that HoCrWO6 exhibit paramagnetic to antiferromagnetic transition at TN = 24 K. The magnetic structure is also determined using neutron diffraction. The magnetic structure represents collinear arrangement of Cr spins and non-coplanar arrangement of Ho spins. The dielectric measurements indicate a weak anomaly at the magnetic transition.
