Previously we studied the effect of Cr spacer layer on in‐plane coercivity in Co/Cr multilayered films. It was found that the high coercivity is related to the easy axis in‐plane orientation and the character of the composition modulation. In this paper, the dependence of the saturation magnetization as a function of Co layer thickness is used to study the interface structure. The layer structure is confirmed by small angle x‐ray diffractometry for typical films. The magnetic interaction among the grains is studied by examining deviation from the behavior predicted by the Wohlfarth model for noninteracting single‐domain particles.
