Abstract (300 words maximum)
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 HoFeWO6 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 HoFeWO6 crystallizes in polar (non-centrosymmetric and achiral) orthorhombic structure P n a 21. The magnetization measurements indicate that HoFeWO6 exhibit paramagnetic to antiferromagnetic transition at TN = 18 K. The dielectric properties at room temperature indicate that the dielectric constant decreases with an increase in frequency indicating the low-frequency dielectric behavior are dominated by the external effects such as interface polarization.
