Abstract: Preparation of acicular maghemite containing dopants like Mg, Ni and Gd and their characterisation using different analytical techniques have been reported. These investigations reveal that the addition of dopants like Mg, Ni and Gd modifies the magnetic properties without effecting any structural changes. The optical bandgaps of these doped compositions have also been determined. Evidence is also available from spectroscopic investigations suggesting that maghemite prepared via the oxalate precursor route does not exhibit a hydrogen ferrite structure.
