Abstract

Polycrystalline samples of BaCexGd1-x03 have been prepared with 0.10 < x < 0.20. X-ray powder diffraction indicates the samples contain only one crystalline phase for doping levels < 0.15. Transmission electron microscopy analyses on the 10% doped sample revealed no glassy phases in the intergranular regions. Single crystal fibers were prepared by Laser Heated Pedestal Growth (LHPG) from the polycrystalline samples. Fiber growth was non-conservative thus the single crystal quality was limited. Preliminary conductivity measurements on the polycrystalline samples using AC impedance spectroscopy are compared with literature data.
