Abstract

The effects of additional doping by beryllium (Be) on the properties of Ga1-xMnxAs were discussed. It was found that the curie temperature increased with an increase in the Be concentration. The magnetoimpurity scattering model described the temperature dependence of the resistivity at zero magnetic field.
