ABSTRACT
Ferromagnetics, ferroelectrics, and ferroelastics are the three types of primary ferroics. These were discussed in the previous three chapters. In this chapter we consider secondary and higher-order ferroics. There are six types of secondary ferroics: ferrobielectrics, ferrobimagnetics, ferrobielastics, ferroelastoelectrics, ferromagnetoelectrics, and ferromagnetoelastics. Still higher order ferroics can be defined by referring to Eq. 6.2.18.
