Research / Activities

Research in this FRG is directed towards the fabrication and study of magnetic and superconducting metamaterials. In particular, we focus on periodically ordered magnetic composites, also called magnonic crystals. Similar to photonic crystals, their magnonic counterparts display band structure properties. As a consequence magnonic crystals are predicted to significantly control the flow of spin density waves and are interesting candidates for novel spin injection and transfer concepts in spintronics.

We develop and use various new template/infiltration methods to fabricate magnonic and superconducting metamaterials. Highly ordered periodic templates are fabricated by self-assembly of different building blocks such as polymers, nanoparticles, and nano/microspheres. These templates are then infiltrated with magnetic and/or superconducting compounds using a wide array of techniques including electrodeposition, high-pressure technique, nanoparticle infiltration, and sol-gel chemistry.

In order to characterize and study the structure of our samples we apply a range of state-of-the-art techniques such as electron microscopy, focused ion beam, optical micro-spectroscopy and X-ray diffraction. In addition, we have several specialty tools and methods to our disposal to study magnetic and electronic properties. They include ferromagnetic resonance, inverse Hall-effect, Brillouin light scattering, a SAGNAC spectrometer for magneto-optical Kerr effect, and Faraday rotation measurements.
