Ferroelasticity and related properties of crystals

Vinod K. Wadhawan
- 01 Jan 1982 -

Jan Petzelt, +2 more
- 01 Jun 1987 -

Evidence for strain-induced ferroelectric order in epitaxial thin-film KTaO3.

M. Tyunina, +6 more
- 01 Jun 2010 - 
TL;DR: The existence of strain-induced ferroelectric order in quantum paraelectric KTaO3 is demonstrated by combining experimental investigations of epitaxial K TaO3 films and density-functional-theory calculations, and it is suggested that a region of short-range polar order might appear in the strain-temperature phase diagrams.

Optical detection of symmetry breaking on a nanoscale in SrTiO3:Ca

Wolfgang Kleemann, +3 more
- 01 Nov 1997 - 
TL;DR: In this paper, spontaneous and field-induced linear birefringence is measured at low temperatures on singledomained single crystals of weakly doped SrTiO3:Ca (x = 0·002 and 0·007) in order to investigate polar ordering processes near to Tc ≈ 4 and 18 K, respectively.

M. DrDomenico, +1 more
- 01 Feb 1969 - 
TL;DR: In this article, a microscopic tensor theory of the electro-optical and nonlinear optical effects in oxygen-octahedra ferroelectrics is presented, which stresses the importance of the basic BO6 octahedron building block in this class of materials.

Polaritons: the electromagnetic modes of media

D L Mills, +1 more
- 01 Jul 1974 - 
TL;DR: In this article, a detailed discussion of the properties of bulk polaritons in an isotropic dielectric, with a single infrared active optical phonon is given, and the phonon and photon strength functions, which provide a useful means of characterizing the polariton are introduced.

Polarization Fluctuations and the Optical-Absorption Edge in BaTi O 3

S. H. Wemple
- 01 Oct 1970 - 
TL;DR: In this article, the authors showed that the band gap in BaTi is at most a weak function of temperature and that it does not display critical behavior, which is consistent with several recent experiments in displacive ferroelectrics.
