Abstract
We study the Josephson effect in a clean superconductor-ferromagnet-superconductor junction for arbitrarily large spin polarizations. The Andreev reflection at a clean ferromagnet-superconductor interface is incomplete, and Andreev channels with a large incidence angle are progressively suppressed with increasing exchange energy. As a result, the critical current exhibits oscillations as a function of the exchange energy and of the length of the ferromagnet and has a temperature dependence which deviates from the one predicted by the quasiclassical theory.
