Hard magnetic materials properties

Table 10. Properties of Permanent (Hard) Magnet Materials ...

In the section 2 of this chapter, an introduction is given to the main concepts required for the understanding of coercivity in hard magnetic materials. The various types of hard nanostructures and the procedures used for their preparation are described in section 3. The specific properties of hard nanostructure magnetism are described in section 4. In section 5, the properties of industrial materials are presented and some applications are briefly summarised. 

Fig. 35. Comparision of the hard magnetic properties of two hard magnetic materials a and b. (Left) Flux density B (full lines) and magnetic polarization J (dashed lines) as a function of the demagnetizing field strength H. (Right) Product BH (horizontal axis) plotted versus B (vertical axis) for both materials a and b. The working point corresponding to (BFf)max is indicated on the B(H) curve (left point for material a and b) by a filled and open circle, respectively.
