abstract
In-plane single domain and vortex magnetization configurations of the magnetic dot in the hybrid superconductor-ferromagnet system are considered. Single domain configuration energy shift due to the presence of superconductor is calculated. The change of the phase curve of the ferromagnetic dot magnetization due to the repulsion of the magnetic field by the superconductor is obtained. Up to the two-fold decrease of the ferromagnetic dot critical radius due to the presence of the superconductor is predicted. 2006 Elsevier B.V. All rights reserved.
