  Superconductivity and magnetism are usually the conflicting (competing)
phenomena. We show, however, that in nanoscopic objects the electron pairing
may promote the magnetic ordering. Such situation is possible at low
temperatures in the quantum dots placed between the conducting and
superconducting reservoirs, where the proximity induced electron pairing
cooperates with the correlations enhancing the spin-exchange interactions. The
emerging Kondo resonance, which is observable in the Andreev conductance, can
be significantly enhanced by the coupling to superconducting lead. We explain
this intriguing tendency within the Anderson impurity model using: the
generalized Schrieffer-Wolff canonical transformation, the second order
perturbative treatment of the Coulomb repulsion, and the nonperturbative
numerical renormalization group calculations. We also provide hints for
experimental observability of this phenomenon.
