Just musing around the word Ferroelectric, I was expecting perhaps something related to iron in the PZT but it's lead, zirconium, titanium, and oxygen. So I learned that Ferromagnetic simply means "iron-like magnetic" and that ferroelectric was coined by analogy to the hysterisis curve of ferromagnets in a magnetic field (MH curve) but in ferroelectric it's an electric field (P-E curve).
