Memory Effect in the Photoinduced Femtosecond Rotation of Magnetization in the Ferromagnetic Semiconductor GaMnAs
J. Wang, I. Cotoros, X. Liu +4
We report a femtosecond response in photoinduced magnetization rotation in the ferromagnetic semiconductor GaMnAs, which allows for detection of a four-state magnetic memory at the…
Distribution of magnetic domain pinning fields in GaMnAs ferromagnetic films
Jungtaek Kim, D. Y. Shin, Sanghoon Lee +2
Using the angular dependence of the planar Hall effect in GaMnAs ferromagnetic films, we were able to determine the distribution of magnetic domain pinning fields in this material.…
GaMnAs-based hybrid multiferroic memory device
M. Overby, A. Chernyshov, L. P. Rokhinson +2
A rapidly developing field of spintronics is based on the premise that substituting charge with spin as a carrier of information can lead to new devices with lower power consumptio…
Definitive Evidence of Interlayer Coupling Between (Ga,Mn)As Layers Separated by a Nonmagnetic Spacer
B. J. Kirby, J. A. Borchers, X. Liu +3
We have used polarized neutron reflectometry to study the structural and magnetic properties of the individual layers in a series of (Al,Be,Ga)As/(Ga,Mn)As/GaAs/(Ga,Mn)As multilaye…
Coherent Magnetization Precession in GaMnAs induced by Ultrafast Optical Excitation
J. Qi, Y. Xu, N. Tolk +3
We use femtosecond optical pulses to induce, control and monitor magnetization precession in ferromagnetic Ga0.965Mn0.035As. At temperatures below ~40 K we observe coherent oscilla…
Magnetic Anisotropy, Spin Pinning and Exchange Constants of (Ga,Mn)As films
Ying-Yuan Zhou, Yong-Jin Cho, Zhiguo Ge +3
We present a detailed investigation of exchange-dominated nonpropagating spin-wave modes in a series of 100 nm GaMnAs films with Mn concentrations ranging from…
