PE loop Ferroelecric Test System

Polarization is a property of certain crystals which are naturally electrically polarized and as a result contain large electric fields. Polarization can be described as the ability of certain materials to generate a temporary voltage when they are heated or cooled. The change in temperature modifies the positions of the atoms slightly within the crystal structure such that the polarization of the material changes. This polarization change gives rise to a voltage across the crystal. If the temperature stays constant at its new value, the Polarization voltage gradually disappears due to leakage current. The system is designed by our company are most advanced in its specifications and can undertake various tests needed by researchers. The complete system is fully automatic with temperature variation and can go down as low as liquid nitrogen. The system also has option to go beyond room temperature with high temperature options such as  500K, 773K and 1073K.
