Prof. Dirk Grundler, Technische Universität München Bio: Dirk Grundler was with the Philips’ Research Laboratories in Hamburg, Germany, from 1990 until the end of 1994 for Diploma and doctorate work on conventional and high-temperature superconductors aiming at sensors for applications in biomagnetism. He qualified as a lecturer in experimental physics at the University of Hamburg in 2001, specializing in spintronics. In 2005 he accepted a professorship at Technical University of Munich, Germany, heading the Chair of Physics of Functional Multilayers. His interests are focussed on correlation effects in low dimensional electron systems and magnonics – a currently evolving research field combining nanomagnetism and spin dynamics. |

Thin-film ferromagnets periodically patterned on the micro- and nanoscale have been shown to form magnonic crystals (MCs), i.e., artificial crystals exhibiting tailored band structures for spin waves (magnons). Their functionality goes beyond e.g. photonic and plasmonic crystals for electromagnetic waves in that the magnetic unit cell allows one to reconfigure the band structure via different non-volatile remanent configurations. MCs thus provide interesting building blocks for microwave applications aiming at both information transmission and processing using spin waves at the nanoscale. To reach this goal, the coupling efficiency between long-wavelength GHz radiation and short-wavelength spin waves needs to be improved. Magnonic crystal-based tranducers might provide a versatile solution to this long-existing problem.
