Ferrite Magnetic Nanoparticles: a Study of the Heating Rate and Specific Power Loss

Under an alternating magnetic field, magnetic nanoparticles have proven to be a viable heating candidate for biomedical and chemical applications. An RF source in conjunction with a water-cooled spiral coil was used to generate the required magnetic fields. The present work investigates heating characteristics of sol-gel processed ferromagnetic Co/Zn/Ni ferrite nanoparticles with different magnetic properties. The observed correlation between the magnetic properties and heating rate will be discussed in this work.
