Abstract

A three-step method has been employed to synthesize 1D core-shell nanostructures consisting of a ferromagnetic Co90Pt10 (CoPt) core and a La doped multiferroic Bi0.87La0.13FeO3 (BLFO) shell. La doping efficiently removes the secondary impurity phases in the multiferroic shell and exchange interaction gives a significant exchange bias effect demonstrating the anti-ferromagnetic functionality of Bi0.87La0.13FeO3.
