摘要: The real and imaginary parts of types I- II-superconductor a-c susceptibility were measured in both parallel perpendicular d-c magnetic fields. A surface superconducting layer with critical field H/sub c3/ was found to exist for external if only barely above the bulk field. Preliminary measurements demonstrating that can a pure material as well an alloy made. (M.J.T.) 21l02 finding transitions samples reduced strontium titanate is reported. occurred at approximates 0.25 0.28 deg K. lt ascertained superconductivity effect. (C.E.S.)
