Description
Although often neglected the coupling of spin and lattice motion plays a role on many length and timescales. Novel spintronic applications aim at controlling magnetization precession and spin currents via lattice strain waves while also angular momentum transfer via the Einstein-de Haas effect can play a role. In this presentation I will give an overview how synchrotrons and x-ray free electron lasers can be used to follow magneto-elastic coupling in non-linear nanoscale magnetic textures. I will also give an outlook how time-resolved electron diffraction promises an interesting alternative to using large-scale facilities.
About the speaker:
Hermann Dürr is a professor at the Department of Physics and Astronomy, FREIA Laboratory in Uppsala University. Before he was a group leader researcher at the Stanford Institute for Materials and Energy Sciences, in SLAC National Accelerator Laboratory.
Prof. Dürr research research encompasses the use of ultrashort (10^-15sec) nonlinear laser, x-ray and electron spectroscopies to probe various aspects of condensed matter systems.
