Abstract:
We suggest that the treatment of the bismuth HTSC ceramics with phenidone provides a chem. reaction between the ceramic surface and the chemisorbed org. mols. accompanied by the extn. of highly labile and weakly bound oxygen from the lattice of the superconducting ceramics. This is confirmed by the IR spectra which show that a phenidone mol. is chemisorbed by >N-H group, and new absorption bands belonging to oxypyrazole (the product of phenidone oxidn.) appear. Thus, an interaction of phenidone with labile oxygen of the bismuth HTSC ceramics occurs which provides changes to its electronic state and consequently, its superconducting properties.
