The goal of this Master project is to create high-quality magnetic multilayers, that have asymmetric depth structures and whose overall magnetic interactions and properties may be modified due to this asymmetric stacking. The purpose of this work is to

• study and classify suitable fabrication conditions 
• understand the resulting magnetic behavior, including the magnetic ground state

These goals are not only of substantial scientific, but also technological interest because all magnetic storage technology today, is based on magnetic films and multilayers with fine-tuned and non-trivial depth structures. Modern fabrication techniques, such as the Ultra High Vacuum Sputter system at CIC nanoGUNE, allow for the precise fabrication of such multilayer structures, in which different ferromagnetic and nonmagnetic layers are alternated and fabricated in stacks with sub-nm precision. 

In the first part of the Master project different ferromagnetic alloy films and related multilayers will be fabricated. Subsequently, their magnetic states will be measured and classified by means of using a magnetic force microscope (MFM) and their field stability will be evaluated with the help of a superconducting quantum interference device (SQUID). The project will involve the fabrication and characterization of samples as well as the analysis of experimental results.  Some prior knowledge of solid-state physics and ferromagnetism will be beneficial.
