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…

Cyclotron Resonance of Itinerant Holes in Ferromagnetic InMnAs/GaSb Heterostructures
G. A. Khodaparast, J. Kono, Y. H. Matsuda +6
We report the first observation of hole cyclotron resonance (CR) in ferromagnetic InMnAs/GaSb heterostructures both in the high-temperature paramagnetic phase and the low-temperatu…
