The Raman scattering of trirutile structure MgTa2O6 single crystals grown by the optical floating zone method

Author affiliations

Abstract

Single crystals of the trirutile structure MgTa2O6 were grown via an optical floating zone method in an air atmosphere. The as-grown crystals were pale yellow and transparent and the natural cleavage plane formed during the crystal growth was determined by XRD2 to be along the c-axis direction. The variations in valence were investigated by XPS (X-ray photoelectron spectroscopy). The room-temperature axis-relative polarized Raman spectra of trirutile MgTa2O6 crystals were described. The order–disorder effect was detected via temperature-dependent Raman spectroscopy.
