Findings
Long-range triplet proximity effect occurs with non-colinear magnetizations.
Josephson current is suppressed in colinear magnetization configurations.
Conditions for dominant triplet contribution are identified.
Abstract
We study the Josephson current through a ferromagnetic trilayer, both in the diffusive and clean limits. For colinear (parallel or antiparallel) magnetizations in the layers, the Josephson current is small due to short range proximity effect in superconductor/ferromagnet structures. For non colinear magnetizations, we determine the conditions for the Josephson current to be dominated by another contribution originating from long range triplet proximity effect.
