Abstract
PURPOSE:To obtain the titled high-temperature superconductor having high critical temperature of superconductivity and usable even under a condition of high magnetic field and electrical current density, by using Y, Ba, Cu and O as principal constituent elements and forming an oxide having mainly amorphous crystal structure. CONSTITUTION:The objective superconductor is composed of an oxide containing Y, Ba, Cu and O as main constituent elements and having mainly amorphous crystal structure. The superconductor can be produced by mixing and melting compounds of Y, Ba and Cu at prescribed molar ratios, quenching the molten mixture at a sufficiently high cooling rate to prevent the deposition of crystal and heat-treating the resultant amorphous material at about <=600 deg.C. The superconductor produced by this process has higher critical temperature than conventional Y-Ba-Cu-O superconductor having a crystal structure of rhombic system. One or more kinds of the main constituent elements (Y, Ba, Cu and O) may be substituted with other elements (e.g. Su or Sr) within a range of <=20atom.%.
