  We present theoretical results on the interplay of magnetic and
superconducting orders in diffusive ferromagnet-superconductor-ferromagnet
trilayers. The induced triplet superconducting correlations throughout the
trilayer lead to an induced spin magnetization. We include self-consistency of
the order parameter in the superconducting layer at arbitrary temperatures,
arbitrary interface transparency, and any relative orientation of the exchange
fields in the two ferromagnets. We propose to use the torque on the trilayer in
an external magnetic field as a probe of the presence of triplet correlations
in the superconducting phase.
