Scaling analysis of the magnetoresistance in Ga_{1-x}Mn_xAs
Scaling analysis of the magnetoresistance in Ga_{1-x}Mn_xAs
We compare experimental resistivity data on Ga_{1-x}Mn_xAs films with theoretical calculations using a scaling theory for strongly disordered ferromagnets. All characteristic features of the temperature dependence of the resistivity can be quantitatively understood through this approach as originating from the close vicinity of the metal-insulator transition. In particular, we find …
