【 摘 要 】
Concentric MnFe2O4-rich core/Cr2O3-rich shell nanoparticles were obtained considering a postsynthetic modification of preformed MnFe2O4@Cr(OH)3 units. The complex nanomaterials display an exchange bias (EB) effect likely due to the interface intermixing and possible cluster spin-glass phase and the presence in the same units of ferrimagnetic and antiferromagnetic-ferroelectric oxides. This particular case of transition metal oxides (TMO) heterostructures underlines the potential of chemical control in their final magnetic properties.
