 
 <prompt> Which one of di following no fit be state wey ferroelectric materials fit dey: paraelectric, cubic or ferroelectric? Based on di last question, write a context wey contain di answer. E fit be 1 - 20 sentences. Context: <response>: Similarly, group theory dey help predict di changes wey dey happen for physical properties wen material dey undergo phase transition, for example, from cubic to tetrahedral crystalline form. One example na ferroelectric materials, where di change from paraelectric to ferroelectric state dey happen for di Curie temperature and e dey related to change from high-symmetry paraelectric state to lower symmetry ferroelectric state, wey dey come with wetin dem dey call soft phonon mode, wey be vibrational lattice mode wey dey go to zero frequency for di transition.
