Magnetic reversal under external field and current-driven domain wall motion in (Ga,Mn)As: influence of extrinsic pinning
K Y Wang, A C Irvine, J Wunderlich +6
We investigate the anisotropy of magnetic reversal and current-driven domain wall motion in annealed Ga_0.95Mn_0.05As thin films and Hall bar devices with perpendicular magnetic an…
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…
Lithographically and electrically controlled strain effects on anisotropic magnetoresistance in (Ga,Mn)As
E. De Ranieri, A. W. Rushforth, K. Vyborny +8
It has been demonstrated that magnetocrystalline anisotropies in (Ga,Mn)As are sensitive to lattice strains as small as 10^-4 and that strain can be controlled by lattice parameter…
Domain walls in (Ga,Mn)As diluted magnetic semiconductor
Akira Sugawara, H. Kasai, A. Tonomura +6
We report experimental and theoretical studies of magnetic domain walls in an in-plane magnetized (Ga,Mn)As dilute moment ferromagnetic semiconductor. Our high-resolution electron…
