Abstract:
The superconducting properties of powdered La 2- x Sr x CuO y were investigated for various values of Sr and oxygen contents. The phase identification by an X-ray diffractometer indicates that the samples have a single-phase K 2 NiF 4 structure. Measurements of the superconducting transition in terms of complex susceptibility χ=χ'-iχ'' have revealed that the sample with x \cong0.16 and y \cong4 has the highest T c . The dependence of χ on the magnetic field amplitude shows different features crossing the value of x ∼0.16, suggesting that for x 〉 0.16, no intrinsic superconducting phase appears, but a low- T c phase may exist for x 〈 0.16.
