Abstract
We report our results on vortex penetration in two realizations of heterogeneos magneto-superconducting systems (HMSS) based on London approach; semi-infinite ferromagnetic(FM)-superconducting(SC) bilayers and a FM dot on a semi-infinite SC film. In the first case, we study quantitatively the vortex entry in FM-SC bilayers which manifests Bean-Livingston-like vortex barrier, controlled by FM film's magnetization and SC film's Ginzburg parameter . In the second case, we investigate the conditions for sponteneous vortex creation and determine the position of vortex for various values of magnetization and the dot's position.
