Volume : II, Issue : X, November - 2012 INFLUENCE OF MN4+ TETRAVALENT SUBSTITUTION ON MAGNETIC VARIATION OF NICKEL FERRITE C.M. KALE, V. K. BAROTE, M.K. BABREKAR, D, E.KAKDE, S.J. SHUKLA Published By : Laxmi Book Publication Abstract : Ferrite sample have general formula Ni Mn Fe O have been prepared by 1+x x 2-2x 4
standard ceramic route and investigated by means of a. c. susceptibility measurement
and Mossbauer spectroscopy. The Mossbauer data and a. c. susceptibility measurements
suggest the Mn4+ ions occupy octahedral (A) and tetrahedral (B) sites. The Mossbauer
spectra at temperature 300K have been fitted with two sextets in the ferrimagnetic state.
The temperature dependence a. c. susceptibility behaviour is attributed to magnetic
anisotropic Ni2+ ions in the system. Keywords : Article : Cite This Article : C.M. KALE, V. K. BAROTE, M.K. BABREKAR, D, E.KAKDE, S.J. SHUKLA, (2012).
