Abstract

We have studied the electrical resistivity and magnetic properties of high-resistance lanthanum and yttrium metal-oxide ceramics. These properties indicate that the superconductivity of such ceramics is due to a network of conducting channels. We found the superconducting gap to be 2Δ ≲ (5.2–5.9) kTc and have measured its temperature dependence and the value of Hc1 for a number of the ceramics.
