Abstract Domain structures of two low coercivity ( H c / H k ≈ 0.02) and one medium coercivity ( H c / H k ≈ 0.05) films were observed by the colloid-scanning electron microscopy (SEM) method in d.c. magnetic fields applied normal to the surface. The dependence of the submicron domain period on ascending and descending fields was measured. Anhysteretic curves were obtained by the superposition of a slowly decreasing a.c. field on the given d.c. field. The field dependence of the anhysteretic domain period is compared with the theory of Kooy and Enz. In addition to the visual measurement, the domain period was also determined by a two-dimensional Fourier analysis of the SEM photographs.
