Magnetic domains of cobalt monocrystal

Topography (left) and magnetic force distribution for same area (right) of cobalt monocrystal with strong perpendicular magnetocrystalline anisotropy. Right image corresponds to deflection of the nonvibrating cantilever. Domains of closure in the form of flowers are seen on magnetic image.
