The temperature dependence of the longitudinal and transverse conductivity is investigated in HoBa2Cu3O7-δ single crystals with different oxygen concentrations. It is shown that twin boundaries are efficient centers for scattering of normal carriers and suppression of the superconducting state. It is found that the anisotropy of the normal resistivity ρc/ρab(T) is described well in the framework of a universal “1/2 law” for thermally activated hopping conduction. [ABSTRACT FROM AUTHOR] |
