DOCUMENT TYPE: Patent CA Section: 76 (Electric Phenomena) Section cross-reference(s): 57 The present invention relates generally to enhancing crit. c.d. carrying capacity of superconducting materials. The present invention also relates to superconducting structures and to a method of improving superconducting properties of rare earth-alk. earth-transition metal oxide films. The method for producing a thick film includes disposing a precursor soln. onto a substrate to form a precursor film. The precursor soln. contains precursor components to a rare-earth/alk.-earth-metal/transition-metal oxide including a salt of a rare earth element, a salt of an alk. earth metal, and a salt of a transition metal in 31 solvents, in which at least one of the salts is a fluoride-contg. salt, and in which the ratio of the transition metal to the alk. earth metal is >1.5. The precursor soln. is treated to form a rare earth-alk. earth-metal transition metal oxide superconductor film having a thickness >0.8 mm soln. .

DOCUMENT TYPE: Journal CA Section: 76 (Electric Phenomena) To shorten the calcination time in the metal-org. deposition (MOD) process using metal trifluoroacetate (TFA), a new combination of starting materials was developed using the F-free salt of Cu and TFA salts of Y and Ba as a so-called new soln. Also, a new process temp. profile for this soln. was developed as an advanced TFA-MOD process in which a high heating rate was achieved. Consequently, an overall transport Ic value of 210 A and a Jc value of 1.5 MA/cm2 (77 K, Self-field), similar to Ic and Jc values using TFA for all salts, were obtained. To obtain higher Jc performance, the effects of process parameters such as the heating rate in the calcination process for the Jc characteristics were studied. As a result, a YBCO film with a thickness of 1.There are some commonly used reagents with their cas registry numbers 37737-28-3 and 60884-92-6 in this article.2 mm was fabricated on a CeO2/IBAD-Gd2Zr2O7 layer-buffered Hastelloy substrate with D f~7°. The overall Ic value of 251 A (77 K Self-field) corresponding to the Jc value of 2.1 MA/cm2 was achieved by calcination at a heating rate of 2°/min. .
