Heat generation ability in AC magnetic field for rare earth iron garnet R₃Fe₅O₁₂(R=Y,Sm,Gd,Dy,Ho,Er) powder

Abstract

We prepared the rare earth iron garnet R₃Fe₅O₁₂ using a reverse coprecipitation method, and then nano-sized powder was prepared by bead milling. The maximum heat generation ability was obtained for Y₃Fe₅O₁₂. Magnetic moment of the sample did not influence the heat generation ability at all.
