Herman Dürr (Uppsala University): "Controlling spins in space and time"

Physikalisches Kolloquium

Polarized soft x-rays have been used for several decades at synchrotron light sources to obtain fascinating new insights into nanoscale magnetism. The now available polarized soft x-ray pulses from x-ray free electron lasers with sub-100 femtoseconds duration allow us to observe the magnetic interactions at work on their natural length and timescales. I will give an overview how such time-resolved studies help to understand the fundamental speed limits for nanoscale spin motion.
