DOI: 10.1080/00150193.2020.1713333
Abstract: Abstract The analytical solutions of spontaneous polarization, phase transition temperature TC, and ferroelectric limit temperature Th have been solved based on the Landau-Devonshire eight-order potential. According to the analytical solutions, the eighth-order potential gives a… read more here.
