Solid solutions of the type Y(Cu0.5Ti0.5) 1-xMxO3 with a hexagonal structure were prepared for M = Mn, Fe, Cr, Al, Ga, and In. A complete solid solution could be obtained only in the case of M = Mn. The green color of YCu0.5Ti 0.5O3 was found to be enhanced by small substitutions of Al, Ga, and In. All compositions containing Mn were black in color. Suppression of magnetic transitions is observed upon co-doping of Cu/Ti into YMnO 3. Measurements of dielectric constant suggest some magneto-electric coupling may be present in the Y(Cu0.5Ti0.5) 1-xMnxO3 solid solution.
