Tuning of the ultrafast demagnetization by ultrashort spin polarized currents in multi-sublattice ferrimagnets
Deeksha Gupta, Maryna Pankratova, Matthias Riepp +11
Femtosecond laser pulses can be used to induce ultrafast changes of the magnetization in magnetic materials. Several microscopic mechanisms have been proposed to explain the observ…

Laser induced ultrafast Gd 4f spin dynamics at the surface of amorphous CoxGd100-x ferrimagnetic alloys
Matthias Pacé, Deeksha Gupta, Tom Ferté +8
We have investigated the laser induced ultrafast dynamics of Gd 4f spins at the surface of CoxGd100-x alloys by means of surface-sensitive and time-resolved dichroic resonant Auger…
