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 factor with high accuracy. The Landé factor increases from to to as the temperature increases from 5 to 100 to 150 K. The experimental results are in the opposite direction than prediction by theory manifesting the need for appreciable, temperature dependent corrections of this band model.
