    <dcterms:abstract xml:lang="eng">We study the changes of magnetoresistance induced by controlled thermal annealing at temperatures ranging from 300to600°C of a Ga&lt;sub&gt;0.98&lt;/sub&gt;Mn&lt;sub&gt;0.02&lt;/sub&gt;As alloy grown by low-temperature molecular beam epitaxy. We use a resistor-networkmodel for describing the electrical transport as a function of temperature and external magnetic field. The model is founded on classical semiconductor band transport and neglects many-body interactions. The peculiarities of dilute magnetic semiconductors, in particular, the magnetic-field induced changes of the density of states and the potential fluctuations due to the giant Zeeman splitting in the paramagnetic phase as well as spontaneous magnetization effects in the ferromagnetic phase, are accounted for in a mean-field fashion. This empirical transport model based on reasonable assumptions and realistic material parameters yields a satisfactory quantitative description of the experimentally obtained temperature and magnetic-field dependence of the resistivity of the entire series of annealedGa&lt;sub&gt;0.98&lt;/sub&gt;Mn&lt;sub&gt;0.02&lt;/sub&gt;As samples, which exhibit metallic, semiconducting, and almost insulating transport behavior with increasing annealingtemperature. Our analysis provides further understanding of the annealing-induced changes of the transport properties in dilute magnetic III-Mn-V semiconductors.</dcterms:abstract>
