A strong scientific interest has driven the fundamental research on magnetic nanoparticles in the last decades [1][2][3][4], with interest constantly fed by their wide range
different magnetic anisotropy opens interesting perspectives for applications in biomedical fields (e.g., MRI, drug delivery, hyperthermia) [20][21] and energy harvesting.
Experimental
Synthesis
Several samples consisting of manganese ferrite nanoparticles with different cobaltdoping, i.e., Mn1−xCoxFe2O4
control over particle size. Nevertheless, our study evidences that a significant change in the magnetic properties occurs in the concentration range between 0 and 25% of cobalt, while subtler variations occur due to incremental additions of Co in substitution of Mn.
Conclusion
The effect of cobaltdoping
