Abstract :
Magnetic and self-heating properties of CoFe2O4, MgFe2O4 and NiFe2O4 nanoparticles were evaluated. MgFe2O4 and NiFe2O4, whose coercive forces are lower than that of CoFe2O4, exhibited higher temperature rise in self-heating excited by ac magnetic field of 150 Oe at 10 kHz. The energy efficiency of magnetic field in generating self heating of these ferrite nanoparticles is also analyzed. It was also evaluated the cytocompatibility of each ferrite nanoparticles.
