摘要：
The paper presents the magnetic properties of Fe3O4 nanoparticles used in hybrid biomaterials, showing the difference between the ferrite nanopowder and the bulk one. The samples, measured by the vibrating sample magnetometer VSM-7304 Lake Shore include materials composed by ferrite nanoparticles coated with sodium alginate or chitosan biopolymers. The results show the superparamagnetic behaviour of the nanoparticles and allow the computing of the average size of the magnetic nanoparticles.
