In fact, i want to know that before and after the permittivity peak(curie temp.) permittivity Vs time curve shows very low permittivity as compared to the peak value both before and after curie temp.
but polarisation was high before curie temp and low after. how can i understand the interrelation between polarisation and permittivity mathematically and conceptually?
My guess: Isn't one the derivative of the other?
If yes, the answer is obvious.
Yeah it is one derivative but i want to understand its physical meaning. the time you have polarisation in the sample then why we don't have a high dielectric constant.
may be before Tc domains are randomly aligned and after Tc new cubic phase vanishes polarisation. but is this true for all the samples in the world
