Magneto-optical properties of vacancy-defective Mn-ferrite films

Optical absorption and Faraday rotation of vacancy-defective spinel Mn-ferrite thin films Mn 1.18Fe 1.82O 4+δ were studied in the visible and near-infrared regions. To introduce cation vacancies the films were oxidised between 150 C and 475°C. The resulting decrease of the absorption brought about t...

Zusammenfassung:Optical absorption and Faraday rotation of vacancy-defective spinel Mn-ferrite thin films Mn 1.18Fe 1.82O 4+δ were studied in the visible and near-infrared regions. To introduce cation vacancies the films were oxidised between 150 C and 475°C. The resulting decrease of the absorption brought about the figure of merit of oxidised samples below 480 nm superior to that of the original Mn-ferrite films.
