Abstract

A new polar and magnetic oxide, YCrWO₆, was successfully synthesized and characterized. YCrWO₆ crystallizes in polar orthorhombic space group Pna2₁ (no. 33) of edge-sharing dimers of CrO₆ and WO₆ octahedra, which are connected by corner-sharing to form a three-dimensional framework structure with Y³⁺ cations located in the channels. The structure of YCrWO₆ is related to that of CaTa₂O₆; however, the ordering of Cr³⁺ and W⁶⁺ in the octahedral sites breaks the inversion symmetry of the parent CaTa₂O₆ structure. X-ray absorption near edge spectroscopy of YCrWO₆ confirmed the oxidation state of Cr³⁺ and W⁶⁺. Temperature-dependent optical second harmonic generation measurements on YCrWO₆ confirmed the noncentrosymmetric character and evidenced a noncentrosymmetric-to-centrosymmetric phase transition above 800 °C. Piezoresponse force microscopy measurements on YCrWO₆ at room temperature show strong piezoelectric domains. Magnetic measurements of YCrWO₆ indicate antiferromagnetic order at T_N of -22 K with Weiss temperature of -34.66 K.
