project summary

            In this project we propose the investigation of thin films with potential future applications in the field of memory devices and reduced-scale engineering. Multilayer, magnetic films where exchange coupling between dissimilar phases can be used to tailor the magnetic response. Perpendicular exchange coupled composite or exchange spring media have recently been introduced as candidate systems in which the magnetic response can be controlled. Perpendicular exchange spring systems, systems on which we will focus, consist of exchange-coupled hard and soft magnetic layers with respectively out-of-plane and in-plane easy magnetization axes. Our approach is a complex one covering the theoretical and the experimental study of the investigated thin film spring magnets.
