FTIR and EPR Studies of Nickel Substituted Nanostructured Mn Zn Ferrite

Abstract

The spinel ferrite system Mn 0.5 - x Ni x Zn 0.5 Fe 2 O 4 is prepared by coprecipitation method. XRD analysis confirms the formation of ferrite phase in all the samples. The FTIR spectra of all the samples show two main absorption bands below 1000 cm −1 . FTIR studies reveal cationic exchange between A site and B site. The magnetic moment calculated from EPR studies is lower when compared to the theoretical values. This confirms the existence of noncollinear magnetic structure arising due to spin canting at B site.
