An “exciting and enlightening revisionist history” (Walter Isaacson, #1 New York Times bestselling author) that upends the myth of the 1950s as a decade of conformity and celebrates a few solitary, brave, and stubborn individuals who pioneered th

We report a new process to fabricate melt-textured YBa 2 Cu 3 O 7−δ superconductors. The highest heating temperature during the melt-textured growth process is 950°C, which is below the melting point of silver, thus making it possible to fabricat

The remanent magnetization in single crystals of YBa 2 Cu 3 O 7−δ has been measured at 77 K as a function of the applied magnetic field orientation relative to the sample. The remanent magnetization was generated by an externally applied field of

Measurements of the intensity and direction of the remanent magnetization have been performed on single-crystal YBa 2 Cu 3 O 7−δ samples at 77 K. In the directions parallel and perpendicular to the Cu-O plane, the remanent magnetization has very d

The scaling properties of the electrical conductivity (Σ) are studied in a binary composite system consisting of metallic silver (Ag) and ceramic copper oxide (YBa 2 Cu 3 O 7-δ ). A percolation transition is observed when p, the volume fraction of

1/f noise experiments performed on Y 1 Ba 2 Cu 3 O 7−δ single crystals indicate that (1) the normalized noise spectral density Sυ/V2 is much larger than that of metals; (2) the temperature dependence of Sυ/V2 differs from that of the resistivity

By monitoring the electrical resistivity of single phase polycrystalline Y1Ba2Cu3O7-δ samples while changing their oxygen content in both ozone and ordinary oxygen environments, we were able to investigate the correlation between their average oxyge
