Spectroscopic Characterization of Ba(Mg1/3Ta2/3)O3 Dieffectrics for the Application to Microwave Communication

摘要：

The lattice vibrational modes of the Ba(Mg1=3Ta2=3)O3 materials, possessing dieffectric 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 γj value for FTIR peaks and vice versa.
