  • Finding ways to achieve higher values of the transition temperature, T c, in superconductors remains a great challenge. The superconducting phase is often one of several competing types of electronic order, including antiferromagnetism and charge density waves. An emerging trend documented in heavy-fermion and organic conductors is that the maximum T c for superconductivity occurs under external conditions that cause the critical temperature for a competing order to go to zero. Recently, such competition has been found in multilayer copper oxide high-temperature superconductors (HTSCs) that possess two crystallographically inequivalent CuO 2 planes in the unit cell. However, whether the competingmore » electronic state can be suppressed to enhance T c in HTSCs remains an open question. Here we show that pressure-driven phase competition leads to an unusual two-step enhancement of c in optimally doped trilayer Bi 2Sr 2Ca 2Cu 3O 10+╬┤ (Bi2223). We find that T c first increases with pressure and then decreases after passing through a maximum. Unexpectedly, T c increases again when the pressure is further raised above a critical value of around 24 GPa, surpassing the first maximum. The presence of this critical pressure is a manifestation of the crossover from the competing order to superconductivity in the inner of the three CuO 2 planes. We suggest that the increase at higher pressures occurs as a result of competition between pairing and phase ordering in different CuO 2 planes.« less
  • The effect of various parameters on superconductivity enhancement produced in tin by current injection of quasiparticles is studied. The data obtained are compared with the results of experiments, carried out for aluminum, and with theoretical calculations/sup 2,3/. The experimental value of the maximum relative gap increase delta..delta../..delta../sub 0/ is significantly below the theoretical value.
