| Abstract: | Ferrimagnetic Y3Fe5O12 powder was synthesized by a reverse coprecipitation method in order to study its heat generation property in an AC magnetic field. An orthorhombic YFeO3 phase having a small particle size (<100 nm) was obtained for the samples calcined at a low temperature. The maximum heat generation ability in an AC magnetic field was obtained for the Y3Fe5O12 ferrite powder by calcination at 1100 °C. The heat generation ability was reduced for the samples calcined at a higher temperature. The particle growth with the formation of the cubic single phase might influence the heat generation ability. The heat generation ability and the hysteresis loss value were proportional to the cube of the magnetic field (H3), because the coercivity value of the B–H curve was proportional to the square of the amplitude of the AC magnetic field (H2). The heat generation ability (W g−1) of the Y3Fe5O12 sample sintered at 1100 °C can be expressed by the equation 2.2×10−4∙f∙H3 using the frequency (f/kHz) and the magnetic field (H/kA m−1), which has the highest heat generation ability of the reported magnetic materials. The hysteresis loss value for the B–H curve agreed with the heat generation ability of the samples calcined at 1100 °C and lower temperatures. |
