The proximity effect in mesoscopic ferromagnet/superconductor (FS) Ni/Al structures of various geometries was studied experimentally on both F- and S-sides of the structures. Samples with a wide range of interface transparency were fabricated. The dependence of the effect on FS interface transparency was investigated. The amplitude of this effect was found to be larger than expected from classical theory of proximity effect. Preliminary experiments showed no phase-sensitive oscillations in Andreev interferometer geometry. Various theoretical models are discussed.
