Abstract

On the basis of the previous structural and electrical examinations it has been found that thin, especially discontinuous Mn films even under vacuum conditions are quickly oxidized. In order to protect from this process just after evaporation of Mn films, its were in vacuo covered with MgF₂ layers. The influence of MgF₂ dielectric layers with thickness d_d approximately equals 21 nm on the optical properties of Mn films was investigated. The thicknesses of Mn films varied from 4 to 32 nm. Optical properties of double films (Mn + MgF₂) differ distinctly from those of single Mn-films. Dielectric layers with thickness d_d approximately equals 21 nm protect from oxidation process and cause an increase of reflection coefficients and decrease of transmission coefficients in the visible and infrared range.
