Soft-mode spectroscopy: Experimental studies of structural phase transitions
TL;DR: In this article, the experimental studies of displacive phase transitions in solids are summarized, focusing on inelastic light scattering and neutron scattering; related infrared reflectivity measurements, as well as x-ray and EPR analyses are also summarized.
Journal ArticleDOI
Structural phase transitions I. Landau theory
TL;DR: In this paper, a review of the application of the Landau-Ginzburg theory to a wide variety of different phenomena which can occur at structural phase transitions is given, in particular, emphasis is placed on the nature of the fluctuations within Landau GINZburg theory and on the role of secondary order parameters.
Journal ArticleDOI
Dynamics of order-disorder-type ferroelectrics and anti-ferroelectrics
TL;DR: In this paper, a pseudo-spin wave theory for order-disorder-type ferroelectrics and anti-ferro-electrics is proposed. But the pseudo-Ising model is not suitable for the case of the non-ising model.
Journal ArticleDOI
Ising model in a transverse field. I. Basic theory
TL;DR: In this article, a brief review of the spin-iIsing model in a transverse field provides a useful description (insulating magnetic systems, order-disorder ferroelectrics, cooperative Jahn-Teller systems and other systems with 'pseudo-spin'- phonon interactions).

Structural phase transitions III. Critical dynamics and quasi-elastic scattering
Alastair D. Bruce,R. A. Cowley +1 more
TL;DR: The results of scattering experiments revealing this phenomenon are surveyed in detail, and are used in an assessment of current theories, subdivided into three categories: those which seek to describe the phenomenon within an extended phonon-based theory; those which attempt to trace the effect to the formation of long-lived clusters of precursor order; and those which associate the quasi-elastic scattering with crystal imperfections as mentioned in this paper.
