Abstract
We report formation of new noncentrosymmetric oxides of the formula, R3Mn1.5CuV0.5O9 for R = Y, Ho, Er, Tm, Yb and Lu, possessing the hexagonal RMnO3 (space group P63cm) structure. These oxides could be regarded as the x = 0.5 members of a general series R3Mn3−3xCu2xVxO9. Investigation of the Lu–Mn–Cu–V–O system reveals the existence of isostructural solid solution series, Lu3Mn3−3xCu2xVxO9 for 0 < x ≤ 0.75. Magnetic and dielectric properties of the oxides are consistent with a random distribution of Mn3+, Cu2+ and V5+ atoms that preserve the noncentrosymmetric RMnO3 structure.
