Infrared absorption in spinel ferrites

The IR spectra of a number of ferrites, MFe sub(2)O sub(4), M(Mn, Fe, Co, Ni, Cu and Zn ) have been studied at room temperture in the range 200-100 0 cm super(-1). In all the cases the spectrum consists of four bands, two of which have strong absorption while the other two have weak absorp tion and...

Description
Summary:The IR spectra of a number of ferrites, MFe sub(2)O sub(4), M(Mn, Fe, Co, Ni, Cu and Zn ) have been studied at room temperture in the range 200-100 0 cm super(-1). In all the cases the spectrum consists of four bands, two of which have strong absorption while the other two have weak absorp tion and often appear as shoulders on the main band. However up to 20 % of the inverse ferrite, the shoulder in the low energy side appears as a band. In this paper we have analysed the origin of the obove bannads.
