We investigated the magnetic field dependence of the longitudinal resistivity ?xx, the Hall resistivity ?xy, and the Hall angle (?H) at various temperatures of fully textured (Hg0.9Re0.1)Ba2CaCu2O6 ? (HgRe-1212) thin films prepared by pulsed laser deposition (PLD) and post-annealing. The films exhibit sharp superconducting transitions at Tc = 124 K with transition widths of ?Tc 2 K. At higher fields the Hall resistivities of the films have a nearly linear dependence on the field. The sign ...We investigated the magnetic field dependence of the longitudinal resistivity ?xx, the Hall resistivity ?xy, and the Hall angle (?H) at various temperatures of fully textured (Hg0.9Re0.1)Ba2CaCu2O6 ? (HgRe-1212) thin films prepared by pulsed laser deposition (PLD) and post-annealing. The films exhibit sharp superconducting transitions at Tc = 124 K with transition widths of ?Tc 2 K. At higher fields the Hall resistivities of the films have a nearly linear dependence on the field. The sign of the Hall resistivity in the low-.eld region near the transition temperature becomes negative. The total Hall conductivity for HgRe-1212 HTSC thin films can be described well by ?yx(B) = C1/B C2B C3.» weiterlesen» einklappen
