We review the main mechanisms of the interplay between magnetism and
superconductivity and discuss first for the properties of the bulk magnetic
superconductors. In the case of ferromagnetism, its antagonism with
superconductivity leads to spectacular effects such as a re-entrant
superconductivity and the domain magnetic structure formation. We also discuss
the particularities of the proximity effect in superconductor-ferromagnet
heterostructures: the damped oscillatory behaviour of the Cooper pair wave
function and the conditions for the novel Pi-Josephson junctions formation,
which open an interesting perspective for the potential applications of these
structures.
