Femtosecond Demagnetization and Hot Hole Relaxation in Ferromagnetic GaMnAs
J. Wang, L. Cywinski, C. Sun +3
We have studied ultrafast photoinduced demagnetization in GaMnAs via two-color time-resolved magneto-optical Kerr spectroscopy. Below-bandgap midinfrared pump pulses strongly excit…

Ultrafast demagnetization in the sp-d model: a theoretical study
L. Cywinski, L. J. Sham
We propose and analyze a theoretical model of ultrafast light-induced magnetization dynamics in systems of localized spins that are coupled to carriers' spins by sp-d exchange inte…

Ultrafast Quenching of Ferromagnetism in InMnAs Induced by Intense Laser Irradiation
J. Wang, C. Sun, J. Kono +4
Time-resolved magneto-optical Kerr spectroscopy of ferromagnetic InMnAs reveals two distinct {\em demagnetization} processes -- fast ( ps) and slow (100 ps). Both compone…
