Abstract
We have prepared a superparamagnetic colloid by milling magnetite particles and evaluated its heating capabilities in an alternating magnetic field wi th frequency 3.5 MHz. As has been found relaxation losses are able to heat superparamagnetic suspension to approximate to 80 degrees C in about 3 min. This result may be of an importance for the design of a new efficient hype rthermic material for cancer treatment.
