Hysteresis loop and characteristic values

After consideration of the different measurement methods we now focus on typical measurement types which are all based on one of the voltage excitation methods but differ in the excitation and the electrical treatment signal in between repeated measurements. 

Pr+ positive state of remanent polarization of the dynamically measured hysteresis loop 

Prrei+ positive state of relaxed remanent polarization, relaxed for one second in the Pr+ state. Equal to the positive state of remanent polarization of the quasi statically measured loop (see Section 3.3.4) 

Pmax+ state of polarization when the stimulating signal reaches its maximum value - positive saturation 

Vc+ positive coercive voltage, voltage where the polarization crosses the rr-axis by increasing voltage values
