Above-Bandgap Magneto-optical Kerr Effect in Ferromagnetic GaMnAs
C. Sun, J. Kono, Y. Cho +3
We have performed a systematic magneto-optical Kerr spectroscopy study of GaMnAs with varying Mn densities as a function of temperature, magnetic field, and photon energy. Unlike p…
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…
Photo-induced precession of magnetization in ferromagnetic (Ga,Mn)As
Y. Hashimoto, H. Munekata
Precession of magnetization induced by pulsed optical excitation is observed in a ferromagnetic semiconductor (Ga,Mn)As by time-resolved magneto-optical measurements. It appears as…
Ultrafast optical manipulation of ferromagnetic order in InMnAs/GaSb
J. Wang, G. A. Khodaparast, J. Kono +3
We have performed a two-color time-resolved magneto-optical Kerr effect (MOKE) study of a ferromagnetic InMnAs/GaSb heterostructure. We observed ultrafast photo-induced changes in…
Ferromagnetic semiconductor (In,Ga,Mn)As with Curie temperature above 100 K
T. Slupinski, H. Munekata, A. Oiwa
We have grown (InyGa1-y)1-xMnxAs ferromagnetic semiconductor layers with Mn composition x up to 0.13 on InP substrates by molecular beam epitaxy. Near the lattice-matched compositi…
