Abstract

The magnetoresistance for charge transport along the c-axis is negative in Bi₂Sr₂CaCu₂O_8+δ, unlike the in-plane transport. We show that Δρ{variant}_c0/ρ{variant}_c is thermally activated with a gap Δ that varies from 520 K to 997 K as the doping proceeds from under-to over-doped. We suggest that the applied field lowers the barrier impeding c-axis charge transport, by coupling to the Zeeman energy.
