We present systematic temperature-dependent resistance noise measurements on a series of ferromagnetic ${\mathrm{Ga}}_{1−x}{\mathrm{Mn}}_{x}\mathrm{As}$ epitaxial thin films covering a large parameter space in terms of the Mn content $x$ and other variations regarding sample fabrication. We infer th...
