Abstract
Zinc ferrite nanowires inside an AAO template is fabricated using a novel technology different from electrodeposition. The physical and chemical properties of the nanowires is investigated by TGA, IR, XRD, SEM and SQUID. The nanoparticles embedded into the pores exhibited superparamagnetic behavior with the blocking temperature of 15 K. However, after annealing, the particles formed nanowires and the hysteresis of the annealed samples increased significantly. Microwave properties of the ferrites are studied using ferromagnetic resonance technique and the change in the resonant curve linewidth due to annealing is observed.
