On October 23rd and 24th, SPICE hosted the 29th REIMEI and ERATO-SQR workshop. The organisers Junichi Ieda and Jairo Sinova brought together leading theorists and experimentalists to work on effects of the spin-orbit interaction and the coupling of the spin and lattice degrees of freedom in magnetic nanostructures.
Being an efficient spin current detector and generating so-called spin-orbit torques on proximity magnets, the spin Hall effect has moved into the mainstream of magnetism. The electrical and thermal actuation of the magnetization of insulators with extremely high quality factors of the magnetization dynamics has focused attention on the bosonic degrees of freedom in spintronics and the importance of the spin-lattice and spin-rotation couplings.
The scope of the workshop covered the topics:
The magnon-phonon interaction in a magnetic insulator (YIG) to better understand acoustically induced spin pumping and the spin Seebeck effect.
Materials with large spin-orbit interaction examined by combining density functional theory in the local density approximation with the quantum Monte Carlo technique.
The effects of spin-orbit interaction on the magnetization dynamics of ferro-, feri-, and antiferro-magnets and their heterostructures.
Thanks to an initiative of Denise and the help of our universally talented student assistant and Bavaria enthusiast Alex, SPICE and the INSPIRE group hosted their own Oktoberfest and likely the first Oktoberfest in the history of Spintronics. From the traditional Oktoberfest-Bier, an especially tasty brew that is only available during the Oktoberfest season to the appropriate Bavarian music and Weißwurst (white sausage), all the essentials had been organised. Thus it is not surprising that, even if neither binge drinking nor any dancing on the tables were observed (as customary at the original event), the ambiance was great. In the midst of a public which was just as international as the one in Munich, our guest Barry Zink had the opportunity to experience some German local colour.
On September 29th we had the pleasure to welcome Barry Zink from the Department of Physics and Astronomy at the University of Denver. He is an expert on micro- and nanofabrication techniques used to control and measure the thermal, magnetic and electronic properties of systems in order to study the fundamental physics of new materials. We thank Barry for an inspiring day of scientific exchange and a very interesting talk on Thermal Spin Injection in Non-Local Spin Valves, Spin Transport in Native FM-Oxides, and Large Spin Hall Angle in Gold Thin Films.
