Abstract

The Faraday rotation and optical absorption of the Co- and Ti-substituted barium hexaferrite thin films measured in the 500–2000 nm wavelength range at room temperature are presented together with the results of the Faraday rotation measurements carried out on selected samples at 80 K. The spectral dependences of the Faraday coefficient are described and interpreted using a set of optical electron transitions belonging to either cobalt or iron cations occupying the tetrahedral and/or octahedral positions in the spinel blocks of hexagonal ferrite crystal lattice.
