Abstract

Chemically synthesized highly crystalline lanthanum strontium manganite LaSrMnO3 and Eu-doped Y2O3 and their composites yielding nanoparticles of size 30-40 nm are reported in this paper. Magnetic measurements performed on the synthesized nanoparticles and composites showed a magnetic transition at about 370 K with a superparamagnetic behavior at room temperature. The ferromagnetic resonance studies of the nanoparticles showed large linewidth due to surface strains. The composite nanoparticles also displayed luminescent behavior when irradiated with ultraviolet light. The manganites as well as their composite with the luminescent nanoparticles may be very useful for biomedical applications. For this possible application, the nature and effects of the nanoparticles in a biological environment have been studied as such particles are known to be toxic.
