Crystallochemical Analysis

On-line resistance measurement in a temperature range of 78 K to 124 K was performed on epitaxial thin films of YBCO irradiated with 140 MeV Si ions. The superconducting transition temperature (T c ), resistivity at 100 K (ρ 100 k ) and transition width (ΔT c ) all show peak at a fluence of 1.5×1013 ions/cm2. A crystallochemical analysis based on metastability induced charge and spin fluctuation due to irradiation induced oxygen disorder in the CuO chains explains the T c enhancement in the low fluence regime.

AbstractThe effects of oxygen and helium ion irradiation on the superconducting properties of Tl2Ca2Ba2Cu3010 thin films were investigated. The transition temperature and width were monitored as a function of ion fluence using both magnetization and resistivity measurements. These data suggest that superconductivity is completely suppressed at 0.020 dpa for both He and 0 ion irradiation. Further, the rate of decrease in Tc as a function of deposited energy showed that the dominant mechanism causing damage-induced suppression of Tc in these films was from atomic collisions.
