Abstract

The paper presents the magnetic properties of some ferrite nanoparticles (Fe₂O₃, CoFe₂O₄ and Fe₃O₄) used in hybrid biomaterials, showing the difference between the magnetic behaviour of ferrite nanopowder and the bulk one. The samples, measured by the vibrating sample magnetometer VSM-7304 LakeShore include materials composed by ferrite nanoparticles coated with various biopolymers. The results show the superparamagnetic behaviour of the nanoparticles and the effect of the ferrite-polymer coupling.
