Abstract

Measurements of the temperature dependence of the optical absorption edge, E_g(T), in EuO, at the close vicinity of its critical temperature, T_c, are reported. In agreement with theoretical expectations the analysis of the results, with the constraints of continuous E_g and dE_g/dT, yielded the same critical exponents (α = α' ≈ -0.044) and amplitude ratio (|A/Á| ≈ 1.22) as the specific heat data analysis.
