We demonstrate experimentally that lithographically or electrically induced strain variations can produce crystalline AMR components which are larger than the crystalline AMR and a significant fraction of the total AMR of the unprocessed (Ga,Mn)As material. Complete phenomenological AMR expressions are derived and new higher order terms are reported in experiments.

Experimentálně je ukázáno, ze litograficky nebo elektricky ovládané mechanické deformace v (Ga,Mn)As dávají vzniknout velmi silným krystalickým komponentám AMR. Jsou odvozeny úplné fenomenologické vzorce pro AMR.
