Floating Zone Growth of Bi2Sr2Ca2Cu3Oy Superconductor
The crystal growth of high-temperature oxide superconductors has been hampered by the complexities of these materials and the lack of knowledge of corresponding phase diagrams. The most common crystal growth technique adopted for these materials is the so-called “Flux” method. This method, however, suffers from several drawbacks: (i) crystals are often crucible and flux contaminated; (ii) cryst...
متن کاملOptical Floating Zone Growth of Single Crystal r-Fe2O3 from a CaFe4O7-Based Solvent
Large single crystals (Φ 5 × L 33 mm) of hematite (R-Fe2O3) have been grown using a CaFe4O7based solvent and 8 bar of oxygen in a four-mirror optical floating zone furnace in the traveling solvent zone configuration. The crystals grow along the [001] direction, are of excellent quality, and contain no residual Ca contamination from the solvent.
متن کاملCrystal growth of rutile by tilting-mirror-type floating zone method
Mirror tilting effects on the interface shape during crystal growth and on the etch pit density of the grown crystals were studied using a tilting-mirror-type image furnace. With increase of tilting angle of mirrors, convexities of both melt-feed and melt-crystal interface and the etch pit density of the grown crystal were systematically reduced. The melt zone, which is formed during crystal gr...
متن کاملZirconate Pyrochlore Frustrated Magnets: Crystal Growth by the Floating Zone Technique
This article reviews recent achievements on the crystal growth of a new series of pyrochlore oxides—lanthanide zirconates, which are frustrated magnets with exotic magnetic properties. Oxides of the type A2B2O7 (where A “ Rare Earth, B “ Ti, Mo) have been successfully synthesised in single crystal form using the floating zone method. The main difficulty of employing this technique for the growt...
متن کاملFloating-zone growth of KxFe2-ySe2 single crystals
The discovery of superconductivity at temperatures above 30 K in KxFe2-ySe2 compounds has attracted considerable attention [1]. The crystal structure of KxFe2-ySe2 descends from the well-known ThCr2Si2 structure with vacancies at the Fe sites. It was soon found that magnetism and superconductivity coexist in AxFe2-ySe2 (A = K, Rb, and Cs) [2-3]. Even in single crystals which show full shielding...
