The paper reports on controlling the occurrence of different states in multisegmented CoNi/Ni nanowires, with tailored alternating magnetic anisotropy, by using the effect of confinement and interaction between segments. The magnetic configurations i.e. longitudinal, vortices or periodic transversal domains, are imaged by XMCD-PEEM and understood by modelling which reveal the relevance of different factors which should be taken into account to promote the occurrence of magneto-chiral effects controlling different structures.
