Temperature change of various ferrite particles with alternating magnetic field for hyperthermic application

Various ferrites (Fe-, Li-, Ni/Zn/Cu-, Co-. Co/Ni, Ba- and Sr-ferrites) were investigated with respect to their application for hyperthermia. Temperature changes under an alternating magnetic field were observed. The area of hysteresis loop was much larger in the Ba- and Sr-ferrites than for that of the Fe-, Ni/Zn/Cu-, Li-, Co- and Co/Ni-ferrites. Co-ferrite exhibited the most applicable temperature change Delta T= 19.25 K (29.62 W/g s), in distilled water when the field was 110 A/m. (c) 2005 Published by Elsevier B.V.
