Electrical and magnetic properties of the superconducting compounds La (Ba, Sr) CuO and YBaCuO
Abstract
A study of the behavior of the electrical resistance and magnetic properties of high-ohmic metal oxide ceramics based on lanthanum and yttrium indicates that, in these systems, superconductivity is associated with the presence of a network of conducting channels. The width of the superconducting slot 2Delta = (5.2-5.9) kTc, its temperature dependence, and the values of Hc1 are determined for some metal ceramic compounds.
