Abstract
PURPOSE: To make possible obtaining dispersion of magnetization from intensity of reflected light by letting linearly polarized light enter the surface of a magnetic material and measuring the reflection intensity thereof by changing the special position (angle) of polarizer and analyzer more than twice.
CONSTITUTION: When the linearly polarized light having passed through a polarizer P reflects on the surface of a magnetic material S, the plane (b) of polarization rotates by ϕ. When the light passes through an analyzer A whose plane (b) of polarization has rotated by θ, its intensity becomes I(θ.r) = I0COS2(θ - ϕ). I0 denotes the intensity per unit area of reflected light and (r) the position on the radiation plane. The intensity I measured with a detector D is measured as the integrated value of radiation area S. The reflection intensity of the special position of the polarizer and analyzer is measured from the formula of magnetization dispersion (Δϕ)2 by using the intensity A at θ = π/4, the intensity B at θ = 0 and I0S = C, whereby the magnetization dispersion may be readily obtained.
