Abstract: Core–shell structured La0.7Sr0.3CoO3 nanoparticles are synthesized and their magnetic and magneto-transport properties are investigated. In these core–shell La0.7Sr0.3CoO3 nanoparticles, the cores are single-crystalline and ferromagnetic, whereas the shells are noncrystalline and predominantly paramagnetic. Moreover, the insulating-like shells can serve as a good spin tunneling barrier. Therefore, in such a special core–shell structure, the spin-polarized interparticle tunneling is improved due to the existence of shells, which thus induces an enhanced low-field magnetoresistance effect.
