The lattice vibrational modes of the Ba(Mg1/3Ta 2/3)O3 materials, possessing dielectric constants K = 22.2 - 25.5 and quality factor Q × f = 182, 600 - 248, 000 GHz, were characterized by Raman and FTIR spectroscopies. The high-Q materials possess sharpest vibrational modes, viz., smallest full-width-at-half-maximum (FWHM) value for Raman peaks and smallest damping coefficient 7, value for FTIR peaks and vice versa.
