Abstract

Experimental Realization of a Unique Class of Compounds: XY-Antiferromagnetic Triangular Lattices, KAg 2Fe[VO4]2 and RbAg2Fe[VO4]2, with Ferroelectric Ground States. -The title compounds are synthesized by solid state reaction of M2CO3 (M: K, Rb), AgVO3, and Fe2O3 (773 K, 3 d) and characterized by XRD, powder neutron diffraction, and magnetic measurements. The compounds crystallize in the space group P3 with Z = 1 and exhibit a frustrated triangular lattice with antiferromagnetic XY-anisotropies. These unique compounds offer convenient experimental access for optimizing ferroaxial multiferroic materials. -(AMUNEKE, N. E.; TAPP, J.; DE LA CRUZ, C. R.; MOELLER*, A.; Chem.
