Planar hall effect in ferromagnetic (Ga,Mn)As/GaAs superlattices

Förlag: POLISH ACAD SCIENCES INST PHYSICS
The planar Hall effect was used for investigation of magnetic anisotropy in short period (Ca,Mn)As/CaAs superlattices epitaxially grown on (001) oriented GaAs substrate. The results confirmed the existence of low-temperature magneto crystalline anisotropy in the superlattices with the easy magnetic axes directed along the two in-plane (100) directions. Attention is paid to the two-state behaviour of the planar Hall resistance at zero magnetic field that provides its usefulness for applications in non-volatile memory devices.
