Three dimensional Yttrium iron garnet nanoresonators for hybrid magnonics

Technical talk by Georg Schmidt, who did his physics diploma and PhD at RWTH Aachen working on selective CVD growth of Si/SiGe nanostructures. After his PhD he joined Laurens Molenkamp in Aachen as a PostDoc and started the group of spintronics working on spin injection into III/V semiconductors. Together with Laurens Molenkamp he moved to Würzburg in 1999 where he continued this research, extending the effort to II/VI semiconductors and adding the development of high resolution lithography techniques and spin dynamics in metallic systems. In 2004 he did his habilitation on spin injection and spin transport in semiconductors. Among other things he took part in the realization of the first electrical spin injection into a semiconductor light emitting diode and he identified the so-called conductance mismatch as a fundamental obstacle for spin injection into semiconductors from metallic ferromagnets. For this work he received the Bernhard-Hess Dozentur from Regensburg University (2002) and the Rudolph-Kaiser Preis (2005). In 2009 he became full professor for nanostructured materials at Martin-Luther-Universität Halle-Wittenberg. Recently his group developed a process for room temperature deposition of Yttrium iron garnet that allows to fabricate freestanding 3D YIG nanoresonators that hold promise in studying coupling phenomena between magnons, photons and phonons.
