Fabrication of the artificial magnetic structures having targeted properties is the key aspect for getting progress in the realization novel spintronic devices. Chromium is the prototypical spin density wave (SDW) antiferromagnet which attracts considerable attention in the context of its use as a spacer layer in the magnetic multilayer structures showing giant magnetoresistance and the spin-valve effect. Tuning of the SDW periodicity of the thin Cr-based films is therefore of the high importance. Impact of the confinement and the electron structure modification on SDW can be systematically studied by ARPES that allows mapping the SDW periodicity as well as the evolution of the Fermi surface topology. It is shown that the SDW periodicity can be driven by direct modification of the Fermi surface topology as well as by modification of the boundary conditions at the interfaces. That allows probing the interplay between spatial confinement and the Fermi surface topology underling the spin structure of the thin Cr-based films giving ideas how to design the layers with predefined spin structures.
