Magnetoresistance oscillations induced by periodically arranged micromagnets

Ye, P. ; Weiss, Dieter ; Gerhardts, R. ; Nickel, H.


Probing magnetic fields can be done, e.g., by employing the well established Hall effect. Alternatively, we make use of the ballistic motion of electrons in high mobility two-dimensional electron systems (2DES) to probe electrically the stray field of periodically arranged micomagnets. We investigate the magnetoresistance of the 2DES underneath arrays of magnetic strips and magnetic dots ...
