Influence of pulse magnetic fields treatment on optical properties of GaAs based films

Long-term transformations of the optical reflectance of GaAs epitaxial structure under weak magnetic field treatment (B = 60 mT, f = 10 Hz, τ = 1.2 ms, t = 5 min) have been obtained. Optical measurements were performed within the wavelength range 800…1100 nm at 300 K. Non-monotonous changes of re...
