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…
Electronic states and cyclotron resonance in p-type InMnAs and InMnAs/(Al,Ga)Sb at ultrahigh magnetic fields
Y. Sun, F. V. Kyrychenko, G. D. Sanders +5
We present a theoretical and experimental study on electronic and magneto-optical properties of p-type paramagnetic InMnAs dilute magnetic semiconductor alloys and ferromagnetic p-…
Theory of carrier dynamics and time resolved reflectivity in InMnAs/GaSb heterostructures
G. D. Sanders, C. J. Stanton, J. Wang +3
We present detailed theoretical calculations of two color, time-resolved pump-probe differential reflectivity measurements. The experiments modeled were performed on InMnAs/GaSb he…
Propagating Coherent Acoustic Phonon Wavepackets in InMnAs/GaSb
J. Wang, Y. Hashimoto, J. Kono +4
We observe pronounced oscillations in the differential reflectivity of a ferromagnetic InMnAs/GaSb heterostructure using two-color pump-probe spectroscopy. Although originally thou…
