Growth and structural characterization of M-type GdTaO4 single crystal fiber

Abstract: The laser heated pedestal growth technique was used to obtain single crystal fiber of M-type GdTaO4. The fibers were around 3cm long, ∅0.8mm, transparent, colorless and did not exhibit any inclusions. The structural quality of the fibers was evaluated by X-ray rocking curve profiles and X-ray topography. Better quality crystals were grown perpendicular to (010) direction presenting rocking curve FWHM typically around 52arcsec for the reflection. The results confirm that good structural fibers can be successfully obtained by the procedure presented here. [Copyright &y& Elsevier]
