Magnetic study of cerium-iron-transition metal mixed compounds

Abstract

The compounds of cerium-iron-transition element mixed oxides of the type CeFeTO4 have been prepared by a solid-state reaction technique and characterized by XRD pattern. The molar magnetic susceptibility (χM) of the powdered sample has been reported in a wide temperature range (300 to 1100 K). All the materials show a typical ferrimagnetic nature. The slope of asymptotic line yields an average magneton number, which indicates that all the materials are perfectly ionic. The transition ions are Ce3+, Fe2+ and Fe3+ in CeFe2O4; Ce3+, Cr3+ and Fe 2+ in CeFeCrO4; Ce3+, Mn3+ and Fe2+ in CeFeMnO4 and Ce3+, Fe3+ and Co2+ in CeFeCoO4.
