Variations of the positions and strengths of the domain wall pinning centres within an amorphous Co_70.3Fe_4.7Si₁₅B₁₀ ribbon were studied by means of a model for the influence of the surface fields H_p on the process of magnetization of amorphous ribbons. The strongest pinning centres are situated close to the free surface of the ribbon and the strength of the pinning centres decreases towards its centre.
