Abstract
The recent experimental results on the proximity effect
in heterostructures composed of superconducting and ferromagnetic
thin films are reviewed. First, the experimental observation and
investigation of the spin screening effect, i.e., a spin
polarization in the V layer developing in the superconducting
state under the influence of a spin polarization of conduction
electrons in the ferromagnetic layer are discussed. This effect
was predicted theoretically by Bergeret _parsed_et al. [F.S. Bergeret,
A.F. Volkov, and K.B. Efetov, EPL 6669, 174504 (2004)]. Then, the progress concerning the experimental
realization of the superconducting spin switch device based on the
superconductor/ferromagnet proximity effect is presented.
