Mg 4 Nb 2 O 9 single crystals were prepared by the optical floating zone method. While the as-grown were boules polycrystalline and cracked with dimensions of ∅ 5–8 mm× L 91 mm, they contained single crystal regions as large as ∅ 4 mm× L 15 m

Effects of the growth velocity on the crystal growth behavior of Bi_2Sr_2Ca_1Cu_2O_x (Bi-2212) have been studied by floating zone technique. The results show that a necessary condition for obtaining large single crystals along the c-axis is that the

Extremely smooth single crystal YBa 2 Cu 3 O 7− δ “thin” films, 1–3 μm thick, have been successfully grown on YBCO-seeded MgO substrates by liquid phase epitaxy. The morphology study on the as-grown samples has revealed a step-flow growth m

Single crystals of Tb2Fe17 have been grown by Czochralski method cold crucible system. Good-quality crystals can be obtained by using the relative low growth rate and stoichiometrical composition. The single crystalline sample shows a pure hexagonal

The addition of 2–5 wt% KCl to BaCuO2 powder used as a solvent to grow YBa2Cu3O6 + δ crystals by top seeded solution growth (TSSG) was found to reduce the crystallization temperature from 990 to 935°C, to promote growth along the c-axis, to reduc
