Query: Electromagnetic proximity effect controlled by spin-triplet correlations
  in superconducting spin-valve structures   The spin-triplet correlations in superconducting spin valve structures
arising in the presence of noncollinear textures of magnetic moment are shown
to enhance strongly the electromagnetic proximity effect, i. e. the long-range
leakage of the magnetic field from the ferromagnet (F) to the superconducting
(S) layer. Both the dirty and clean limits are studied on the basis of the
Usadel and Eilenberger theory, correspondingly. Our results suggest a natural
explanation for the puzzling enhancement of the spontaneous magnetic fields
induced by the noncollinear magnetic structures observed by the muon spin
rotation techniques in a wide class of layered S/F systems. We show that the
electromagnetic proximity effect causes the shift of the Fraunhofer dependence
of the critical current on the external magnetic field in the Josephson
junction with one superconducting electrode covered by the ferromagnetic layer.
This provides an alternative way to measure both the magnitude and the
direction of the spontaneous magnetic field induced in the superconductor. We
also demonstrate the possibility of the long ranged superconductivity control
of the magnetic state in F$_1$/S/F$_2$ structures.
