ABSTRACT
Exchange-bias coupling was first discovered in core–shell nanoparticles; however, subsequent research efforts have been devoted mostly to thin films. Recently, there has been renewed interest to obtain a deeper understanding of this phenomenon in core–shell nanoparticles. Advances in chemical synthesis and microscopy characterization techniques allow us to correlate subtle and complex changes in structure with the measured magnetic properties. In this chapter, we discuss such correlations by using several different types of core–shell nanoparticles as examples and emphasize the importance of interfacial microstructure on exchange bias.
