We report our results on vortex penetration in two realizations of heterogeneos magnetic superconducting systems (HMSS) based on the 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-type vortex barrier, controlled by FM film's magnetization m and SC film's Ginzburg parameter \ensuremathκ. 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.
