Abstract
We found a new compound in the Bi-Ca-Sr-Cu-O system which has a different structure from the 80 K superconductor Bi2(Ca, Sr)3Cu2O y . The c-dimension of this compound is ∼37 Å and is ∼6 Å longer than that of Bi2(Ca, Sr)3Cu2O y . Although we have not obtained a single-phased sample yet, the clear correlation between the diamagnetic susceptibility just below 110 K and the content of this compound included in the sample strongly suggests that the compound with c≈37 Å is responsible for the superconductivity of T c∼110 K.Keywords
