Lateral magnetic anisotropy superlattice out of a single (Ga,Mn)As layer
R. G. Dengel, C. Gould, J. Wenisch +3
We use lithographically induced strain relaxation to periodically modulate the magnetic anisotropy in a single (Ga,Mn)As layer. This results in a lateral magnetoresistance device w…
Independent magnetization behavior of a ferromagnetic metal/semiconductor hybrid system
S. Mark, C. Gould, K. Pappert +4
We report the discovery of an effect where two ferromagnetic materials, one semiconductor ((Ga,Mn)As) and one metal (permalloy), can be directly deposited on each other and still s…
Detailed transport investigation of the magnetic anisotropy of (Ga,Mn)As
K. Pappert, C. Gould, M. Sawicki +4
This paper discusses transport methods for the investigation of the (Ga,Mn)As magnetic anisotropy. Typical magnetoresistance behaviour for different anisotropy types is discussed,…
An extensive comparison of anisotropies in MBE grown (Ga,Mn)As material
C. Gould, S. Mark, K. Pappert +14
This paper reports on a detailed magnetotransport investigation of the magnetic anisotropies of (Ga,Mn)As layers produced by various sources worldwide. Using anisotropy fingerprint…
Control of magnetic anisotropy in (Ga,Mn)As by lithography-induced strain relaxation
J. Wenisch, C. Gould, L. Ebel +7
We obtain control of magnetic anisotropy in epitaxial (Ga,Mn)As by anisotropic strain relaxation in patterned structures. The strain in the structures is characterized using sophis…
Transport Characterization of the Magnetic Anisotropy of (Ga,Mn)As
K. Pappert, S. Hümpfner, J. Wenisch +4
The rich magnetic anisotropy of compressively strained (Ga,Mn)As has attracted great interest recently. Here we discuss a sensitive method to visualize and quantify the individual…
