Abstract

We have measured the magnetoconductance (MC) defined by Δσ = σ(H)-σ(0) of two-dimensional Bi films subjected to a periodic magnetic field H, which is produced by a superconducting intermediate state of thick Pb film placed in the immediate vicinity of metal films. Non-linear H dependence of MC has been observed at low magnetic fields. This is not expected from a simple magnetic distribution of normal (H = Hc) and superconducting (H = 0) domain structure in the intermediate state. For specimen of which Pb film has sharp edges, MC shows the step-like structure. This indicates the strong surface flux pinning effect. On the other hand, in the case of broad edge of Pb film, MC shows the oscillation behavior.
