Figure 14.14
Scaling behavior of M at various temperatures for present material.
modulus spectra for present material are independent of temperature.
Figure 14.15 yields that the Curie temperature and transition tempera-
ture are the same, and this simply means that the present material exhib-
its a second order phase transition. h e details of this aspect involving
the ferroelectric phase transition are discussed in the topic by Jona and
Shirane.
