Further Information

Electric polarization

Electric polarization is measured by pyro-current technique. 


The charge induced on the sample faces generates current IP via a probe resistor. The current is recorded by a digitizer, and integrated numerically to obtain electric polarization P.


The sample should be shaped as a plane-parallel plate, with a surface area of few square millimeters, and thickness 0.1 – 1 mm. The polling voltage ranges +/- 500 V.
