Landau-Ginzburg thermodynamic theory

Barium titanate is also the first material with the ferroelectricity studied theoretically by Devonshire (1949). Theoretical description is based on the idea of the thermodynamic potentials known from the Landau-Ginzburg theory of phase transitions (Devonshire 1949, 1951). Barium titanate is mainly used in multilayer ceramic capacitors and in positive temperature coefficient (PTC) elements (Bhalla et al. 2000). [Pg.147]

The Ginzburg-Landau theory is equivalent to a mean field theory considering the thermodynamic entity of the dipoles in the mean field of all the others. It is reasonable if the particular... [Pg.18]
