We describe a technique for operational control of the reliability of the data of magnetic circular dichroism spectroscopy in reflected light, which is based on measuring the polar magneto-optical Kerr effect under normal incidence of light on a sample with a method of phase modulation of a light wave using a photoelastic modulator. The presented technique involves measuring the amplitudes of signals at the “zero” (V=) and doubled (V2f) frequency f of the retardation modulation in crossed polarizers in the process of scanning over a spectrum. In these measurements, the constancy of the V2 ̸V= ratio over the entire spectral range confirms the reliability of the spectroscopy data. The possible instrumental errors that lead to a distortion of the recorded spectrum shape were analyzed. The operability and efficiency of the technique is illustrated by an example of measuring the magnetic circular dichroism spectrum of a MnAs film.
