Interface magnetism (FWIN-G)

Our group is investigating magnetic effects at interfaces between different structures. Those structures are created by means of thin film deposition and ion irradiation. One example are metallic multilayers where the magnetic properties are locally taylored by ion irradiation or the magnetic doping of non-magnetic materials. The interface-magnetism-group is working in different projects which are partially funded by external sources (see below).
