Abstract A survey of A′ A ″B′ B ″O 6 double perovskites, which encompasses over 300
compounds synthesized from about 1950 to the present, shows that three distinct B-cation …

The paper will trace the evolution of understanding related to the modification of sharp
ferroelectric phase transition behavior that occurs in composition systems which exhibit …

Dielectric capacitors are very attractive for high power energy storage. However, the low
energy density of these capacitors, which is mainly limited by the dielectric materials, is still …

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 …

A zero‐field spontaneous relaxor‐ferroelectric transition is reported in Pb (Sc0. 5Ta0. 5) O3
(PST). This behavior is different from that of other relaxors, where such transitions occur only …

The structural ordering characteristics of lead magnesium niobate (PMN) and solid solutions
(PMN-PT) of PMN with lead titanate have been investigated using transmission electron …

Tetragonal La‐modified lead zirconate titanate ceramics with a Zr/Ti ratio of 40/60 (x/40/60)
with La contents (x) between 0 and 21 at.% were prepared by the mixed oxide method and …

Transition lines between various phases in the electric-field–temperature phase diagram of
9/65/35 lanthanum-modified lead zirconate titanate ceramics were determined by …

Tetragonal La-modified lead zirconate titanate (PLZT) ceramics (Zr/Ti= 40/60) with La-
contents of 8, 12, and 15at.% have been studied using dielectric spectroscopy, X-ray …

This paper reviews ferroelectric oxides in the unusual condition where the concentration of
electronic carriers is close to a metal–insulator transition; in certain structures and …
