Exploring the impact of the inverse Faraday effect on all-optical helicity-dependent magnetization switching
M. Kohlmann, L. Vollroth, K. Jäckel +7
All-optical helicity-dependent magnetization switching (AO-HDS) is the quickest data recording technique using only ultrashort laser pulses. FePt grains provide an ideal platform f…

Magnetic nutation: transient separation of magnetization from its angular momentum
Anulekha De, Julius Schlegel, Akira Lentfert +6
For nearly 90 years, precession and relaxation processes have been thought to dominate magnetization dynamics. Only recently has it been considered that, on short time scales, an i…

Spin-noise spectroscopy as a tool for probing magnetic order
Julius Schlegel, Martin Evers, Ulrich Nowak
Spin noise spectroscopy is a technique to measure magnetization fluctuations, a subject of increasing relevance in ultrafast spintronics. We investigate numerically the equilibrium…
