Signatures of ballistic and diffusive transport in the time-dependent Kerr-response of magnetic materials
Sanjay Ashok, Jonas Hoefer, Martin Stiehl +4
We calculate the influence of diffusive and ballistic transport on ultrafast magnetization in thick metallic films. When only diffusive transport is present, gradients of magnetiza…

Control of transport phenomena in magnetic heterostructures by wavelength modulation
Christopher Seibel, Marius Weber, Martin Stiehl +5
We demonstrate the tuneablity of the ultrafast energy flow in magnetic/non-magnetic bilayer structures by changing the wavelength of the optical excitation. This is achieved by an…
