Abstract

An overview is given on the experimental evidence of the nonuniform twisted canted state in Fe/Cr ML in the spin-flop phase. The canting angles are maximal in the end layers and progressively relax towards the middle of the ML from both sides. The magnetic moments in the two end layers are tilted in antiphase, which creates an unavoidable stacking fault in the middle. The ML is decomposed into two types of vertical domains with the mirrored configuration of magnetic moments.
