Anisotropy of normal resistivity in oxygen-deficient YBa2Cu3O7−x single crystals

Abstract

Temperature dependences of the resistivity tensor components ρab and ρc were measured for YBa2Cu3O7−x single crystals with different oxygen contents. The resistivity anisotropy ρc/ρab was found to grow exponentially with decreasing temperature. The results are compared with the predictions of different models describing transverse transport in the normal state of cuprate high-T c superconductors.
