    摘要: In order to stably retain an oxide-based melt consisting essentially of yttrium or a lanthanoid element, barium, copper and oxygen at a prescribed temperature with no impurity contamination thereby preparing a large oxide crystal of high quality from the melt, an oxide melt consisting essentially of yttrium or a lanthanoid element, barium, copper and oxygen is stored in a first crucible, which in turn is held in a second crucible. The first crucible is made of a material which is an oxide of at least one element forming the melt having a melting point higher by at least 10.degree. C. than a melt retention temperature and causing no structural phase transition up to a temperature higher by 10.degree. C. than the aforementioned prescribed temperature, with solubility of not more than 5 atomic percent with respect to the melt in a temperature range from the room temperature to a temperature higher by 10.degree. C. than the melt retention temperature. The second crucible is made of a material substantially causing neither melting nor chemical reaction with respect to the oxide-based melt, which can retain the melt more stably than the first material. Even if the melt overflows the first crucible, this overflow is suppressed by the second crucible. It is possible to prepare a crystal of an oxide superconductor such as YBa.sub.2 Cu.sub.3 O.sub.7-x (0.ltoreq.X.ltoreq.1) by the pulling method from the melt which is stored in the first crucible.

    摘要: A composite material comprising a bulky substrate of a Y-series 123 metal oxide crystal, and at least one layer provided on a surface of the substrate and formed of a crystal of a Y-series 123 metal oxide. The substrate may be produced by immersing a seed material in a liquid phase which comprises components constituting the metal oxide. The liquid phase contains a solid phase located at a position different from the position at which the seed material contacts the liquid phase. The solid phase provides the liquid phase with solutes which constitute the Y-series 123 metal oxide so that the solutes are transported to the position at which the seed material and the liquid phase contact, thereby permitting the Y-series 123 metal oxide to grow on the seed material as primary crystals and to obtain the bulky substrate. The layer of a Y-series 123 metal oxide may be formed on the substrate by a sputtering method, a vacuum deposition method, a laser abrasion method, a CVD method or a liquid phase epitaxy method.

    摘要: A RE-type oxide superconducting wire having excellent angular dependence for magnetic field of Jc is obtained by finely dispersing magnetic flux pinning centers into a superconductor. A mixed solution which comprises a metal-organic complex solution including a metal element which composes a RE-type oxide superconductor whose Ba content is reduced and a metal-organic complex solution including at least one or more kinds of metals which are selected from Zr, Ce, Sn, or Ti which has a larger affinity for Ba is coated onto an intermediate layer of a composite substrate, and the assembly is then calcined to disperse artificially and finely oxide particles (magnetic flux pinning centers) including Zr. Thus, the angular dependence for magnetic field (Jc,min/Jc,max) of Jc can be remarkably improved.
