Abstract

Fine Y3Fe5O12 (YIG) powder with self-heat generation ability in an AC magnetic field was prepared by a modified co-precipitation method and calcined at 600–1100 °C. Using this method, a single phase of the YIG ferrite structure was obtained at a low calcination temperature. The heat generation ability of the modified synthesis sample with a particle diameter of ∼120 nm in a AC magnetic field was significantly improved. The correlation between heat generation ability and hysteresis loss was not confirmed for this sample, which suggests that the heat generation of YIG ferrite powder might have been caused by another factor that differs from the magnetic loss.
