In general, the new artificial ultrathin structures that are the basis of these devices are not in thermal equilibrium and structurally evolve in time upon heating. As these structural changes also affect the magnetic properties, it is both of technological and fundamental interest to understand this evolution. The main focus of this thesis has been on the thermal stability of ultrathin magnetic metallic multilayers. Already before annealing some striking aspects of the investigated structures were discovered. The first one was the strong dependency of the magnetic hardness of a thin CoFe layer on its Ru buffer layer thickness. The second was the large difference in properties between the seemingly similar Cu/Co/Ru and Ru/Co/Cu magnetic layers. Upon annealing of the three material combinations, CoFe/Ru, Co/Ru and Co/Cu, common aspects (like defect elimination and granularization) could be found in their structural evolution as well as clear differences (like strong mixing and high stability). The findings and their understanding have been successfully confirmed and improved by micromagnetic and 2D kinetic Monte Carlo computer simulations. In addition, the rate of change in both experiments and simulations showed the same time dependency that nicely is described by both the free volume model and the trapping model. Furthermore, in this work a combination of various techniques is used to investigate the evolution of the magnetic, electric and structural properties of the multilayer structures. One of these is the new interface sensitive technique of Magnetization induced Second Harmonic Generation (MSHG) that is demonstrated to be directly interface magnetization sensitive and correlated to the interface roughness.","Radboud University, 28 februari 2005","Promotor : Rasing, T.H.M.","171 p."]},{"key":"dc:title","label":"Title","values":["Thermal stability of ultrathin magnetic metallic multilayers"]}]}],"canonical_facts":{"dc:contributor":["Rasing, T.H.M."],"dc:creator":["Bal, K."],"dc:date":["2005"],"dc:description":["Contains fulltext : 33153.pdf (Publisher’s version ) (Open Access)","With the possibility to make high quality atomic scale magnetic multilayer structures (nanotechnology), new phenomena have been discovered like Interlayer Exchange Coupling, Giant Magneto Resistance (GMR) or Tunnel Magneto Resistance (TMR).
