Temperature and magnetic field dependence of the Hall effect in the normal and mixed state of fully textured (Hg0.9Re0.1)Ba2CaCu2O6 ? (HgRe-1212) HTSC thin films prepared by laser ablation deposition have been studied. The longitudinal resistivity ?xx and Hall resistivity ?yx of HgRe-1212 superconductor thin films were measured for a wide range of magnetic fields from 125 mT to 12 T with the field perpendicular to the ab plane and the current in the ab plane.

(HgRe-1212) HTSC thin films prepared by laser ablation deposition have been studied. The longitudinal resistivity ?xx and Hall resistivity ?yx of HgRe-1212 superconductor thin films were measured for a wide range of magnetic fields from 125 mT to 12 T with the field perpendicular to the ab plane and the current in the ab plane. A sign change of the Hall resistivity is observed in fields below 3 T in the region close to the superconducting onset temperature. The temperature dependencies ?xx ? T and ?yx ? 1/T have been observed for HgRe-1212 thin films. The Hall angle ?H relation cot ?H = ?T2 ?, remains valid for temperatures T between Tc and 200 K. In the mixed state a power-law behavior is observed, where ?yx scales to a power-law function of ?xx: , with ? increasing from 1.0 to 1.7 as the field increases from 1 to 12 T. » weiterlesen» einklappen
