✦ Synopsis

We have measured critical currents in Pb/Ge multilayers as a function of direction and magnitude of a magnetic field ning at the Pb Ge interfaces.

The critical current as a function of a perpendicular field displays a pronounced P erpendicular to the current. The higher J, for a field parallel to the layers indicates flux pinmaximum at low fields. TEM reveals Pb nrain sizes of about 1000 A and indicates that the enhanced flux pinning may be explained by grain bound&y pinning.

It is shown, within a simple model calculation, that the critical current density of an S/N/S junction in a high paralel magnetic field decays exponentially. The comparison of the theoretical results with experimental data for the Pb/Cd/Pb junction and YBCO films is given.
