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

Epitaxial (001) BiFeO 3 thin films with tetragonally stained structures and a c / a ratio of about 1.04 were fabricated on single crystalline (100) Rh substrates. The BiFeO 3 thin film showed high remanent polarization ( P r ) of about 91 μC/cm 2 .

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 effects of processing YBa 2 Cu 3 O x (Y123) superconductor in the near-zero gravity (0 g ) environment provided by the NASA KC-135 airplane flying on parabolic trajectories were studied. A new sheet float zone furnace, designed for this study, en

A phase diagram of the system CaF 2 −YF 3 was constructed from the data obtained in thermal analysis, annealing and quenching experiments. Five phases were found in the system: (a) continuous solid solutions Ca 1- x Y x F 2+ x with a limit value of
