Abstract
In this communication, we report the synthesis and characterization of organic-capped core/shell CoFe2O4/MnO nanoparticles. Magnetic properties of the core/shell nanoparticles were compared to those of individual CoFe2O4 and MnO nanoparticles prepared with similar methods. Magnetic measurements revealed that the core/shell nanoparticles displayed a shift in the hysteresis loops corresponding to exchange biasing exchange fields of about 0.6 kOe, due to the ferrimagnetic/antiferromagnetic interface.Keywords
