Magnetic materials are ubiquitous in current electronics, sensors and power systems. Controlling magnetic properties of materials using the least energy possible is therefore currently a key challenge for basic research. Magnetic materials also constitute some of the highly tuneable materials systems currently being studied. Understanding their dynamics and fundamental nanoscale physics is crucial for finding ways in which electronic and magnetic order can be efficiently controlled. A small change in the electronic structure, induced either by interfaces or using spatial confinement can substantially change the material characteristics and induce new emerging phenomena.
The objectives of the research group are the following:
i) research focused on how the spatial confinement affects magnetic and electronic phase transitions in nanomagnets and heterostructures of functional materials,
ii) studying the dynamic behavior of magnetic nanostructures driven by magnetic field, electric field, electric current, strain, temperature gradients and ultrafast laser pulses,
iii) formation of new functional systems by assembling individual structures with well controlled properties into 2D and 3D arrays to design magnetic materials with tuneable properties.
Specific expertise of the research group includes
- magnetism on the nano- and mesoscale, magnetization reversal and dynamics
- magnetoelectric transport properties
- magnetic x-ray microscopy and spectroscopy
- magnetic force microscopy
- magneto-optical characterization and microscopy
- synthesis and analysis of properties of (epitaxial) magnetic films
