Abstract

Half metallic ferromagnetic Chromium Oxide (CrO 2 ) with 100% spin polarization is thought as an excellent candidate for magnetic nano-tag for Giant magnetoresistive biosensor. We have investigated the chemical synthesis and direct mixing approaches for the synthesis of Ag@CrO 2 core shell nanoparticles. For chemical synthesis two mild reducing agents namely polyvinyl alcohol (PVA) and ethylene glycol (EG) were used. Our investigations suggest that the direct mixing and subsequent annealing at 300°C for 2 h is the better method to realize Ag@CrO 2 core shell nanoparticles.
