Summary:The paper investigates the ellipsometric method of measuring the magneto-optical parameter and optical constants in one experiment at affixed angle of the light incidence in ferromagnetics. The influence of the magnetization modulation on the change of ellipsometrical angles is shown. The method is considered for the geometries of polar, meridional and equatorial reflection Kerr effects. The formulae relating to the measured signals in polarizer-subject-analyzer (PSA) circuit with four magneto-optical and optical constants illustrated by the example of ferromagnetic Ni are given.
