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…
Phonon-induced long-lasting nonequilibrium in the electron system of a laser-excited solid
Sebastian T. Weber, Baerbel Rethfeld
Electron-electron thermalization and electron-phonon relaxation processes in laser-excited solids are often assumed to occur on different timescales. This is true for the majority…
Femtosecond formation dynamics of the spin Seebeck effect revealed by terahertz spectroscopy
T. S. Seifert, S. Jaiswal, J. Barker +18
Understanding the transfer of spin angular momentum is essential in modern magnetism research. A model case is the generation of magnons in magnetic insulators by heating an adjace…
