Abstract

The c-axis resistivity c in Bi2Sr2CaCu2O8 and oxygen-reduced YBa2Cu3O6+x is quite sensitive to a magnetic field H. The magnetoresistance (MR) is large (1% at 14 T and 100 K), weakly anisotropic, and negative over a wide range of temperatures T above the critical temperature Tc. The magnitude of the MR is activated in temperature with a characteristic energy UL that varies with the oxygen content. We interpret the activated form of c and the negative MR in terms of a pseudogap that is slightly reduced by H.
