The angle-dependent behavior of the magneto-resistance of a series of low-temperature molecular beam epitaxy grown Ga0.98Mn0.02As samples on (311)A-GaAs-substrates is studied. The samples are annealed at different temperatures in a range from 300 °C to 500 °C, which leads to a redistribution of the manganese in the sample and finally to the formation of MnAs clusters. As a consequence, the ...
