“…In general, optical constants depend on the growth conditions of the films, 64 weight ratio, 65 structure of the film, 66 and different assumptions made in the analysis of the data. The measurements by Angadi and Thanikaimani 65 on MnBi films and by Stoffel and Schneider 67 on MnAs films reveal a considerable aging effect of the optical constants.…”

The magneto-optic ͑MO͒ Kerr and Faraday spectra for manganese pnictides are calculated using the all electron, relativistic, full-potential linear muffin-tin orbital method. The amplitude of our calculated spectra are found to be in good agreement with corresponding experimental spectra. Although the MO property is a rather complicated function of the diagonal and off-diagonal elements of the optical conductivity tensor, present theory nevertheless provides very practical insight about its origin in these compounds. The largest Kerr effect observed in MnBi can be understood as a combined effect of maximal exchange splitting of Mn 3d states and the nearly maximal spin-orbit ͑s-o͒ coupling of Bi. The frequency-dependent optical properties, namely reflectivity, absorption coefficient, electron-energy-loss spectra, refractive index, extinction coefficient are given. From our calculations ͑including spin-orbit coupling and orbital polarization͒ the site-projected spin and orbital moments are also obtained and compared to the available experimental values and a good agreement is found. The magnetic anisotropy energy is calculated with a minimal number of approximations for the three systems. A disagreement between theory and experiment is found. Using the generalized gradient corrected fullpotential linear augmented plane-wave method we have calculated the unscreened plasma frequencies and the hyperfine parameters such as electric-field gradient as well as the hyperfine field. ͓S0163-1829͑99͒01419-8͔

The optical spectra of MnV compounds (V = P, As, Sb, Bi) do not yield unambiguous evidence on the absorption mechanisms beyond that expected from one-electron excitations in a spin-polarized energy band description, although the scattering of the conduction electrons indicates strong d-electron correlations; in particular, since the scattering is comparable to that of s-electrons on open 3d and 4f shells a decomposition of the 3d4 cation state into extended and quasi-localized electron states is suggested.Zur Deutung der optischen Spektren von MnV-Verbindungen (V = P, As, Sb, Bi) sind bisher Annahmen uber Absorptionsmechanismerl, die uber Einelektronenanregungen in einem spinpolarisierten Energiebandschema hinausgehen, nicht notwendig geworden. Die Streuung der Leitungselektronen laBt sich dagegen eher mit der Streuung von s-Elektronen an offenen 3d-und 4f-Schalen vergleichen. Dies deutet auf starke Wechselwirkungen zwischen den d-Elektronen hin und auf eine Aufteilung des 3d4-Kationenzustandes in ausgedehnte und quasi-lokalisierte Zustande.
