The whole of science is nothing more than a refinement of everyday thinking. Science is the attempt to make the chaotic diversity of our sense experience correspond to a logically uniform system of thought. Albert Einstein

4.1 Introductory Remarks

The term ferroelectrics arose by analogy with ferromagnetics, mainly because they have similar characteristics: under electric fields for ferroelectric phenomena and under magnetic fields for ferromagnetic phenomena. The prefix ferro- derived from ferum, which means iron in Latin. The term is perfect for ferromagnetics, since all ferromagnetic phenomena are associated with the special type of spin arrangement of the iron atoms. But in ferroelectrics ...
