  We report on a study of the temperature-dependence of current-induced
effective magnetic fields due to spin-orbit interactions in the diluted
ferromagnetic semiconductor (Ga,Mn)As. Contributions from the effective fields
as well as from the anomalous Nernst effect are evident in the difference
between transverse resistance measurements as a function of an external
magnetic field for opposite orientations of the applied current. We separately
extract these contributions by fitting to a model of coherently rotating
magnetization. The component of the effective field with Dresselhaus symmetry
is substantially enhanced with increasing temperature, while no significant
temperature-dependence is observed for the component with Rashba symmetry.
