  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 $m$ and SC film's Ginzburg parameter
$\kappa$. 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.
