Simulation of hysteresis loops for polycrystalline ferroelectrics by an extensive Landau-type model

Landau-type phenomenological theory is extended to the polycrystalline ferroelectrics by defining a volume fraction of polarization to simulate polarization hysteresis loops. Using this simple model, polarization hysteresis loops of a model Pb(Zr0.52Ti0.48)O3ceramic at different fields or temperatur...
