Query: Ballistic transport in ferromagnet-superconductor-ferromagnet trilayers
  with arbitrary orientation of magnetizations   Transport phenomena in clean ferromagnet-superconductor-ferromagnet (FSF)
trilayers are studied theoretically for a general case of arbitrary orientation
of in-plane magnetizations and interface transparencies. Generalized
expressions for scattering probabilities are derived and the differential
conductance is computed using solutions of the Bogoliubov-de Gennes equation.
We focus on size and coherence effects that characterize ballistic transport,
in particular on the subgap transmission and geometrical oscillations of the
conductance. We find a monotonic dependence of conductance spectra and
magnetoresistance on the angle of misorientation of magnetizations as their
alignment is changed from parallel to antiparallel. Spin-triplet pair
correlations in FSF heterostructures induced by non-collinearity of
magnetizations are investigated by solving the Gor'kov equations in the clean
limit. Unlike diffusive FSF junctions, where the triplet correlations have a
long-range monotonic decay, we show that in clean ferromagnet-superconductor
hybrids both singlet and triplet pair correlations induced in the F layers are
oscillating and power-law decaying with the distance from the S-F interfaces.
