In 1880, the brothers Jacques and Pierre Curie were studying the phenomenon of pyroelectricity
Very large piezoelectric coefficients had been discovered in Rochelle salt, and single crystals several centimeters in size were being grown at the time by General Electric (GE)
The concept of “ferroelectricity” was first mooted as a theoretical possibility by Erwin Schrodinger in 1912,7 Valasek has indicated that his first awareness of the use of the term as applied to materials that possessed an electrically switchable spontaneous dielectric polarization was by Hans Mueller [Massachusetts Institute of Technology (MIT)] in 1940.8 At first, the effect was thought to be connected to the presence of polar water molecules and hydrogen bonding
Summary
In 1880, the brothers Jacques and Pierre Curie were studying the phenomenon of pyroelectricity. The switchable spontaneous polarization of ferroelectric materials confers upon them many useful properties with an extraordinarily wide range of applicability; some examples include:
