ABSTRACT
Magnetic Nanoparticles of Fe3O4 doped by different amounts of Y3+ (0, 0.1, 1 and 10%) have been synthesized by chemical route. Single phase formation has been confirmed by X-Ray diffraction measurement. An improved magnetisation has been observed in SQUID-VSM measurement for the Fe3O4 sample with1% Y3+ doping.The surface morphology and particle size distribution have been confirmed by SEM and TEM measurements. The results obtained are suggestive of the suitability of Y3+ doped Fe3O4 Nanoparticles for biomedical applications specially for hyperthermia treatment.
