Abstract:
Superconductivity up to about 110 K in the CrTlSrCaCuO system was observed by resistance and ac susceptibility measurements. Powder X-ray diffraction analyses showed that a 1212-type phase, Cr -substituted TlSr 2 CaCu 2 O 7 , is responsible for the observed superconductivity. This is the first time that single-element substitution for TlSr 2 CaCu 2 O 7 increases T c of the 1212 phase to above 100 K. The Cr -substituted TlSr 2 CaCu 2 O 7 is easily prepared and has very good quality suitable for practical applications.
