Abstract

New piezoelectric La₃Ta_0.5Ga_5.5O₁₄ bulk single crystals were grown using the Czochralski technique. The crystal structure (space group P321, a = 8.228(2), c = 5.124(2) angstrom) has been refined using single-crystal X-ray diffraction data with a precision corresponding to an R index of 0.04. Ta atoms were found to be ordered in the octahedral site coordinated by six oxygen atoms.
