Abstract
Magnetic anisotropy and applied fields for hyperthermia applications have been optimized for iron cobalt nanocrystalline particles using numerical micromagnetics. The optimized anisotropy energy is [formula omitted] at 500 KHz and the hysteresis loss at this optimized energy is approximately [formula omitted] for a very small oscillating field of magnitude 10 Oe. We have also investigated the effects of varying the applied field and find that the addition of a 20 Oe static field applied perpendicular to the oscillating field approximately doubles the energy loss without subjecting the patient to additional radiation. This is an important benefit for magnetic hyperthermia.
