AbstractThe magnetic properties of MnZn-ferrite are greatly affected by the distribution and valence state of the magnetic and nonmagnetic metallic ions on the tetrahedral (A) and octahedral (B) sites in the spinel ferrite unit cell. A primary factor which can affect the distribution and valence state of the metallic ions is the stoichiometry of the ferrite. In this paper we report on the results of the site occupancy of the transition metal ions in a series of MnZn-ferrite films using extended x-ray absorption fine structure (EXAFS). The EXAFS data are correlated with the film composition and those magnetic properties which are sensitive to the ionic distribution (e.g., magnetic anisotropy field and magnetization) in order to confirm the use of EXAFS as a technique for the investigation of metallic ion distribution in spinel ferrites.
