D. Sedmidubsky et al., INFLUENCE OF COMPOSITION ON TRANSPORT-PROPERTIES OF BI2-XSR2-YCU1O6+DELTA, Physica. C, Superconductivity, 235, 1994, pp. 1393-1394
The study of the Bi2-xSr2-yCu1O6+delta series revealed the influence o
f oxygen and bismuth incorporation into the structure on the transport
properties of R-2201 phase. The behaviour is interpreted by the occup
ancy of the O(2) vacant sites in -(SrO)- layers by oxygens and of Sr-s
ites by bismuth ions.
