Abstract :
The cation distribution in MnFe2O4 single crystal films and artificial ferrite structures is determined by a multiple-edge analysis of the extended X-ray absorption fine structure (EXAFS) of the manganese and iron absorption edges. Compared with conventional manganese ferrite films processed by pulsed laser ablation (PLD), artificial ferrites that are constructed by a unique layer-by-layer PLD deposition were found to have inversion parameters as high as 58%. Magnetic properties of these ferrite films are compared as a function of cation inversion.
