Abstract
The reflectivity of magnetite (Fe3O4) has been measured in the spectral energy range between 0.03 eV and 12 eV and analysed in terms of the optical constants. The variation of the reflectivity with temperature in the infrared photon energy range reflects the temperature dependence of the "intraband" transitions of the conduction electrons. Foreover it points to the presence of temperature dependent coupled plasmon-phonon modesKeywords
