Controlling spins in space and time
  Condensed Matter seminars

Tuesday 21 February 2017
from 15:00 to 16:00
at FB42
Speaker : Herrmann Dürr (SLAC and University of Amsterdam)
Abstract : Magnetism is a quantum effect at work in the macroscopic world we live in. As such it has fascinated mankind for millennia and also led to many modern-day applications, very prominently in information processing and storage. 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 in on their natural length and timescales. I will show how the challenges for performing time-resolved XMCD at the Linac Coherent Light Source have recently been overcome and give an overview how such studies help to understand the fundamental speed limits for nanoscale spin motion.
