Title: YCrWO 6: Polar and Magnetic Oxide with CaTa 2O 6-Related Structure

Abstract

Here, a new polar and magnetic oxide, YCrWO 6, was successfully synthesized and characterized. YCrWO 6 crystallizes in polar orthorhombic space group Pna21 (no. 33) of edge-sharing dimers of CrO 6 and WO 6 octahedra, which are connected by corner-sharing to form a three-dimensional framework structure with Y 3+ cations located in the channels. The structure of YCrWO 6 is related to that of CaTa2O 6; however, the ordering of Cr 3+ and W 6+ in the octahedral sites breaks the inversion symmetry of the parent CaTa 2O 6 structure. X-ray absorption near edge spectroscopy of YCrWO 6 confirmed the oxidation state of Cr 3+ and W 6+. Temperature-dependent optical second harmonic generation measurements on YCrWO 6 confirmed the noncentrosymmetric character and evidenced a noncentrosymmetric-to-centrosymmetric phase transition above 800 °C. Piezoresponse force microscopy measurements on YCrWO 6 at room temperature show strong piezoelectric domains. Magnetic measurements of YCrWO 6 indicate antiferromagnetic order at T N of ~22 K with Weiss temperature of -34.66 K.
