High-quality epitaxial (Hg0.9Re0.1)Ba2CaCu2O6 ? HTS thin films were successfully prepared by pulsed laser deposition (PLD) of Hg-free precursor material on (1 0 0)-oriented SrTiO3 substrates with subsequent Hg vapour annealing. (Hg0.9Re0.1)Ba2CaCu2O6 ? HTS thin films exhibit sharp superconducting transitions at Tc?122 K. The electrical resistance for c-axis oriented HgRe-1212 films has been studied as a function of temperature and dc magnetic fields up to 10 T parallel to the crystallographic...High-quality epitaxial (Hg0.9Re0.1)Ba2CaCu2O6 ? HTS thin films were successfully prepared by pulsed laser deposition (PLD) of Hg-free precursor material on (1 0 0)-oriented SrTiO3 substrates with subsequent Hg vapour annealing. (Hg0.9Re0.1)Ba2CaCu2O6 ? HTS thin films exhibit sharp superconducting transitions at Tc?122 K. The electrical resistance for c-axis oriented HgRe-1212 films has been studied as a function of temperature and dc magnetic fields up to 10 T parallel to the crystallographic c-axis. The irreversibility line for the HgRe-1212 has been deduced from the data and investigated as a function of reduced temperature T/Tc. The result of the irreversibility line is compared with published data for other high Tc cuprates. » weiterlesen» einklappen
