Rabi oscillations describe the process whereby electromagnetic radiation interacts coherently with spin states in a non-equilibrium interaction. To date, Rabi oscillations have not been studied in one of the most common spin ensembles in nature: spins in ferromagnets. Here, using a combination of femtosecond laser pulses and microwave excitations, we report the classical analogue of Rabi oscillations in ensemble-averaged spins of a ferromagnet. The microwave stimuli are shown to extend the…

Ultrafast magnetization enhancement in metallic multilayers driven by superdiffusive spin current.
TLDR
Spatially separate the spin dynamics using Ni/Ru/Fe magnetic trilayers and surprisingly find that optically induced demagnetization of the Ni layer transiently enhances the magnetizations of the Fe layer when the two layer magnetizations are initially aligned parallel.

It is shown that a model based on electron-phonon-mediated spin-flip scattering explains both timescales on equal footing and concludes that the ultrafast magnetization dynamics can be well described disregarding highly excited electronic states, merely considering the thermalized electron system.
