Remnant states of sphere-like particles have been investigated for different ferromagnetic metallic materials by numerical micromagnetic calculations in order to establish the critical radius for the monodomain-vortex transition. The obtained radii have been compared with those obtained earlier by order of magnitude estimates and analytical micromagnetic calculations. A hard-axis oriented vortex state has been found as a transition between the monodomain and easy-axis oriented vortex magnetization states.
