Magnetic field modulated photoreflectance measurements are performed on the dilute nitride semiconductor Ga(AsN) in quantizing magnetic fields. From the measured cyclotron energies, the conduction band effective mass and its dependence on the nitrogen content are determined. The effective mass is found to become significantly heavier in samples with high nitrogen composition (>0.1%).
