Abstract

The temperature dependent frequency of quantum beats of free electron Larmor precession in bulk GaAs yields the temperature variation from 5 to 200 K of the Landé g factor with high accuracy. The Landé g factor increases from -0.44 to -0.38 to -0.35 as the temperature increases from 5 to 100 to 150 K. The experimental results are in the opposite direction than prediction by kp theory manifesting the need for appreciable, temperature dependent corrections of this band model.
