We have calculated the optical and magneto-optical properties of ferromagnetics in a wide spectral range hv = 1.24–5.15 eV, by applying theoretical models which were reported earlier literature. This allowed us to find connection between conductivity measured values complex Kerr angle Θ order establish most proper technique for processing experimental data. The behavior dispersion curves diagonal non-diagonal components tensor depends on choice signs imaginary parts refractive index, should...

This work is devoted to Co – O compounds' investigation by the methods of spectroscopic ellipsometry. The article's main problem analysing information about electronic structure cobalt-oxygen compounds in different structural states. Oxygen impurity was chosen because it one atmospheric gases characterized high chemical activity. Co-O were obtained method magnetron sputtering on leicosapphires' substrate cooled liquid helium. Process provided vacuum with gradual adding 2% and 4% oxygen into...
