Thermodynamic desorption of oxygen in high Tc superconducting oxides
We measure as a function of temperature and composition the equilibrium pressure of desorbed oxygen from superconducting oxides MBa2 Cu3 O6+x (M=Eu, Y). Using the Lacher model we determine the enthalphy of formation of the excess oxygen x (-0.7 eV/atom) as well as the repulsive O-O interaction energy (0.11eV). We also observe that there is a spontaneous reabsorption of the oxygen above about 60...
متن کاملHigh-Temperature Superconducting Bandpass Spiral Filter
We report a new type of microstrip bandpass spiral filter structure, which exhibits much smaller size than other existing miniaturized bandpass filter structures, and is particularly useful in developing hightemperature superconducting (HTS) compact filters for cellular communication systems. A prototype three-stage HTS bandpass spiral filter with center frequency of 633 MHz was designed and fa...
متن کاملSuperconducting properties of copper oxide high - temperature
The equations for the magnon pairing theory of high-temperature copper-oxide-based superconductors are solved and used to calculate several properties, leading to results for specific heat and critical magnetic fields consistent with experimental results. In addition, the theory suggests an explanation of why there are two sets of transition temperatures (T, 90 K and Tc 55 K) for the YBa2Cu306+...
متن کاملPhotoinduced Changes in High Temperature Superconducting Films
Photoexcitation experiments performed in oxygen deficient but metallic YBa,Cu,O, c-axis oriented films revealed that the persistent photoinduced enhancement of conductivity and superconductivity are not restricted to the insulating side of the metal-insulator transition. A clear increase of the critical temperature T,, which is accompanied by a decrease of the resistivity in the normal state pa...
متن کاملStatus of High Temperature Superconducting Magnet Development
Since the discovery of high temperature superconductors more than 2 decades ago, there has been interest in their use for future fusion machines. Lack of performance of commercially available materials, however, dampened the initial optimism. However, recent advances in HTS materials, mostly second-generation tapes, open attractive topologies. In addition to reduced cryogenic loads and increase...
