Static reversal process of the magnetization in normal permalloy films of about 800 Å in thickness was investigated by means of the Faraday magneto-optic effect. For films with small anisotropy dispersion (Δ90≃0.1), the splitting into band domains of about 100 μ wide was observed. The appearance of these domains is interpreted by Smith’s model of labyrinth propagation. For films with medium dispersion (Δ90≃0.2~0.3), a new type of partial rotation, the splitting into the slender domains of about 20 μ in width was found to precede the appearance of the band domains. The splitting into the slender domains is interpreted by Middelhoek’s model of partial rotation. The propagation of the labyrinth domain was clearly observed only in the case of large dispersion (Δ90≃0.4).
