The in- and out-of-plane magnetoresistance of a single crystal of YBa2Cu3O7-delta has been measured at temperatures above T(c) in magnetic fields up to 12 T. A Montgomery-type contact configuration was used with corrections for the finite size of the contacts taken into account. For temperatures up to 2.5 K above T(c) the data are well described by both the Aronov-Hikami-Larkin theory for a layered superconductor (applicable only for the in-plane magnetoconductivity) and the Ginzburg-Landau theory for a three-dimensional anisotropic superconductor (applicable for both the in-plane and the out-of-plane magnetoconductivity). All three analyses give consistent results for the coherence lengths.
