    Spin-current-mediated rapid magnon localisation and coalescence after ultrafast optical pum** of ferrimagnetic alloys

    Sub-picosecond magnetisation manipulation via femtosecond optical pum** has attracted wide attention ever since its original discovery in 1996. However, the spatial evolution of the magnetisation is not yet ...

    Ultrafast Spin Dynamics on the Nanoscale

    We summarize the first x-ray free electron laser experiment that determines the extraordinary spin dynamics in the ferrimagnetic alloy GdFeCo on the femtosecond time- and nanometer length-scale. The results sh...

    Nanoscale spin reversal by non-local angular momentum transfer following ultrafast laser excitation in ferrimagnetic GdFeCo

    The dynamics of thin magnetic films revealed by ultrafast laser techniques cannot be explained by standard equilibrium descriptions. Diffraction experiments using an X-ray laser now allow the spin dynamics of ...
