FIR optical properties of single crystal Ba-and Sr-hexaferrite

Far-infrared reflectivity measurements on single crystal barium and strontium hexaferrite are presented. The infrared active TO, and the associated LO phonon frequencies and the dielectric permittivity functions for E ⊥c have been determined using a fitting procedure based on a four parameter model....

Description
Summary:Far-infrared reflectivity measurements on single crystal barium and strontium hexaferrite are presented. The infrared active TO, and the associated LO phonon frequencies and the dielectric permittivity functions for E ⊥c have been determined using a fitting procedure based on a four parameter model. The infrared active modes of these compounds (space group D 4 6h have been determined by group theoretical analysis and the results compared with the spectroscopic measurements.
