Abstract

The non-stoichiometric Nd[Mg<subscript>1/2(1+x)</subscript>Sn<subscript>1/2</subscript>]O<subscript>3</subscript> (NMS, − 0.04 ≤ x ≤ 0.04) were synthesized through a routine solid-state reaction process. The phase composition, phonon characteristics, and microwave dielectric properties were investigated by X-ray diffraction patterns, Scanning electron microscopy Raman and Fourier transform far-infrared reflection. The best crystallinity with uniformly distributed grains and clear grain boundaries at x = 0.01. The intrinsic properties were calculated by four-parameter semi-quantum model based on far-infrared reflectivity data, which agree well with those values obtained from the microscopic polarizabilities & damping coefficient angle. The correlations between intrinsic properties and lattice vibrational modes were discussed in particular. [ABSTRACT FROM AUTHOR]
