The occurrence of metastable or stable domain states on mesoscopic length scales seems
to be a widespread property of many solids undergoing phase transitions in the presence of …

This review summarizes experimental evidence for the freezing of reorienting moments in
solids. The moments may be of dipolar or quadrupolar nature, or both; they belong to one of …

Evidence has been found that the relaxor ferroelectric bears strong resemblance to spin and
dipolar glasses. The dielectric dispersion will be shown to have a characteristic freezing …

The static polarization of lead magnesium niobate has been studied using a standard
Sawyer-Tower circuit. The square-to-slim-loop hysteresis transition was phenomenologically …

In this paper we discuss some of the measurements and properties of materials that are
crystalline ferroelectrics with a glassy polarization phase. We review measurements of the …

In the present paper, dielectric, polarization, and Raman results have been combined to
identify the existence of a ferroelectric phase transition in the substitutionally disordered …

Polarization dynamics and formation of polar nanoregions (PNR) in relaxor ferroelectrics is
considered within a model of interacting short range polar clusters formed by off-center ions …

The field dependence of the dielectric response has been measured for lead magnesium
niobate relaxors. The frequency dispersion of the temperature of the permittivity maximum, T …

Relatively low concentrations of randomly substituted off-center ions are known to induce
ferroelectric order in highly polarizable crystals. In the case of potassium tantalate (KTaO 3) …

The fate of electric dipoles inside a Fermi sea is an old issue, yet poorly explored. Sr 1− x Ca
x TiO 3 hosts a robust but dilute ferroelectricity in a narrow (0.0018< x< 0.02) window of …
