Photo-induced spin dynamics in ferromagnetic semiconductor -(Ga,Mn)As
Y. Mitsumori, A. Oiwa, T. Slupinski +4
Spin dynamics in ferromagnetic -(Ga,Mn)As ( = 0.011, = 30 K) has been studied by carefully comparing the decay time of the photo-induced reflectivity change with the…
Cyclotron Resonance in Ferromagnetic InMnAs/(Al,Ga)Sb Heterostructures
G. A. Khodaparast, J. Kono, Y. H. Matsuda +9
We report the observation of hole cyclotron resonance (CR) in InMnAs/(Al,Ga)Sb heterostructures in a wide temperature range covering both the paramagnetic and ferromagnetic phases.…
Ultrafast Photoinduced Softening in a III-V Ferromagnetic Semiconductor for Non-thermal Magneto-Optical Recording
G. A. Khodaparast, J. Wang, J. Kono +2
Through time-resolved two-color magneto-optical Kerr spectroscopy we have demonstrated that photogenerated transient carriers decrease the coercivity of ferromagnetic InMnAs at low…
Relation among concentrations of incorporated Mn atoms, ionized Mn acceptors, and holes in p-(Ga,Mn)As epilayers
R. Moriya, H. Munekata
The amount of ionized Mn acceptors in various p-type Mn-doped GaAs epilayers has been evaluated by electrochemical capacitance-voltage measurements, and has been compared systemati…
