Anisotropic Current-Controlled Magnetization Reversal in the Ferromagnetic Semiconductor (Ga,Mn)As
Yuanyuan Li, Y. F. Cao, G. N. Wei +8
Electrical current manipulation of magnetization switching through spin-orbital coupling in ferromagnetic semiconductor (Ga,Mn)As Hall bar devices has been investigated. The effici…
Current-driven domain wall motion across a wide temperature range in a (Ga,Mn)(As,P) device
K. Y. Wang, K. W. Edmonds, A. C. Irvine +9
Current-driven magnetic domain wall motion is demonstrated in the quaternary ferromagnetic semiconductor (Ga,Mn)(As,P) at temperatures well below the ferromagnetic transition tempe…
Huge tunnelling anisotropic magnetoresistance in (Ga,Mn)As nanoconstrictions
A. D. Giddings, O. N. Makarovsky, M. N. Khalid +8
We report large anisotropic magnetoresistance (AMR) behaviours in single lateral (Ga,Mn)As nanoconstriction of up to 1300%, along with large multistable telegraphic switching. The…
Singlet-Triplet Physics and Shell Filling in Carbon Nanotube Double Quantum Dots
H. Ingerslev Jørgensen, K. Grove-Rasmussen, K. -Y. Wang +4
An artifcial two-atomic molecule, also called a double quantum dot (DQD), is an ideal system for exploring few electron physics. Spin-entanglement between just two electrons can be…
Control of Coercivities in (Ga,Mn)As Thin Films by Small Concentrations of MnAs Nanoclusters
K. Y. Wang, M. Sawicki, K. W. Edmonds +6
We demonstrate that low concentrations of a secondary magnetic phase in (Ga,Mn)As thin films can enhance the coercivity by factors up to ~100 without significantly degrading the Cu…
Reorientation Transition in Single-Domain (Ga,Mn)As
K-Y. Wang, M. Sawicki, K. W. Edmonds +5
We demonstrate that the interplay of in-plane biaxial and uniaxial anisotropy fields in (Ga,Mn)As results in a magnetization reorientation transition and an anisotropic AC suscepti…
