(a) Isothermal magnetization as a function of applied magnetic field of the (34)3 hexaferrite at selected temperatures. (b) Magnetization as a functions of temperature between 400 and 700 K under an external magnetic field of 30 mT. The Curie temperature is highlighted with a vertical line at TC = 615 K. (c) Curie temperatures of the M-type, Y-type and mixed-layer hexaferrites as a function of the percentage of M block present within their stacking sequences.
