    Superconductivity at 3.5 K in BaPb0.75Sb0.25O3: why is Tc so low?

    SUPERCONDUCTING BaPb0.75Bi0.25O3, with a transition temperature (Tc ) of 12 K (ref. 1), is now widely viewed as the precursor to the recent appearance of copper oxide superconductors with record high Tc S. The ob...

    Specific Heat Linear Term in YBa2Cu3O7−x and a Survey of Related Compounds

    We have measured the specific heat, C, in the temperature range 0.3 to 20K and in magnetic fields up to 12 Tesla of several compounds related to the high-Tc superconductors. The linear term in C for YBa2Cu3O7−x i...

    63,65Cu NMR and NQR in YBa2Cu3O7-δ

    NMR and NQR results are reported for 63,65Cu in YBa2Cu3O7-δ. Analysis of the high-field NMR spectrum indicates substantial disorder in the copper-oxygen planes. Nuclear relaxation rates are significantly differen...

    Substitutions of Divalent Transition Metal Ions in Yttrium Iron Garnet

    Various amounts of the divalent ions of manganese, iron, cobalt, and nickel have been substituted for trivalent iron in yttrium iron garnet. The effect of substitution of Fe2+ or Mn2+ ions in dodecahedral sites h...
