YBa sub(2)Cu sub(3)O sub(7-y) single-crystal growth by the method of horizontally directed temperature gradient

YBCO single crystals 1-2-3 were grown from a melted mixture of YBa sub(2)Cu sub(3)O sub(7-y)-BaO-CuO using the method of horizontally directed cooling in the zone melting equipment. Differences in superconducting properties, parameters of crystal structure and the microstructure were found in single...

Description
Summary:YBCO single crystals 1-2-3 were grown from a melted mixture of YBa sub(2)Cu sub(3)O sub(7-y)-BaO-CuO using the method of horizontally directed cooling in the zone melting equipment. Differences in superconducting properties, parameters of crystal structure and the microstructure were found in single crystals grown in Al sub(2)O sub(3) and ZrO sub(2) crucibles. It is possible that these differences are connected with the different stability of the crucibles used and consequently with the presence of impurities in the melted charge during the single crystal growth process.
