Abstract
We measured the magnetic field dependence of the out-of-plane resistivity (ρc) of Bi2Sr2Ca(Cu1-xZnx)2O8+δ (Bi-2212) single crystals. Magnetic field was applied to a sample along the c axis. With Zn-doping, the out-of-plane resistivity in the normal state and Tc decrease, and the negative magne- toresistance (MR) of the doped sample becomes smaller than the undoped one. These results are compared with the out-of-plane resistivity of Ni-substituted Bi-2212 single crystals: The Zn- substituted sample is more destructive to the superconductivities and suppressive to the semiconductive behavior than the Ni one, but an elastic factor is not so different from another. It implies that induced magnetic moment causes a pair-breaking effect and nonmagnetic impurity Zn fills the pseudogap.
