Thickness-Roughness Phase Diagram of Multilayer Ferromagnet-Antiferromagnet Nanostructures and their Hysteresis Loops

Abstract

For a three layer system consisting of two ferromagnetic layers separated by an antiferromagnetic interlayer it is shown that the stability region of single-domain ferromagnetic layers is technologically dependent on the ratio between the width of interface atomic steps and the thickness of layers. The thickness-roughness phase diagram has three regions: a collinear orientation of the magnetizations of ferromagnetic layers (1) oriented to each other at 9O deg. (2) and a multidomain structure of ferromagnetic layers (3). The proposed approach can be compared with experiment by studying magnetic hysteresis loops against nanostructure layer thicknesses and their roughnesses owing to atomic steps on interfaces.
