“…As-measured hysteresis loops include a background dielectric contribution which makes them appear tilted; this has been subtracted for clarity (Figure S17, Supporting Information, Experimental Section). As previously observed for related systems in the out-of-plane direction, [35,39] both coercive field and remanent polarization decrease as a function of increasing strontium content. Hereafter, we transition to explore bilayer structures beginning with a 50-nm-thick x = 0.6 layer on top of a 50-nm-thick x = 0.4 layer.…”

Exchange‐Interaction‐Like Behavior in Ferroelectric Bilayers

Interlayer coupling in materials, such as exchange interactions at the interface between an antiferromagnet and a ferromagnet, can produce exotic phenomena not present in the parent materials. While such interfacial coupling in magnetic systems is widely studied, there is considerably less work on analogous electric counterparts (i.e., akin to electric “exchange‐bias‐like” or “exchange‐spring‐like” interactions between two polar materials) despite the likelihood that such effects can also engender new features associated with anisotropic electric dipole alignment. Here, electric analogs of such exchange interactions are reported, and their physical origins are explained for bilayers of in‐plane polarized Pb1−xSrxTiO3 ferroelectrics. Variation of the strontium content and thickness of the layers provides for deterministic control over the switching properties of the bilayer system resulting in phenomena analogous to an exchange‐spring interaction and, leveraging added control of these interactions with an electric field, the ability to realize multistate‐memory function. Such observations not only hold technological promise for ferroelectrics and multiferroics but also extend the similarities between ferromagnetic and ferroelectric materials to include the manifestation of exchange‐interaction‐like phenomena.

“…The dielectric constant value of all the BST–BCT ceramic samples increases with rise in temperature and close to Curie temperature it shows a strong anomaly in dielectric constant value, which is a characteristic of ferroelectric behavior. This behavior can be described on the basis of increase in domain wall mobility with rise in temperature …”

The effect of Ba 0.7 Ca 0.3 TiO 3 (BCT) substitution on the structural, dielectric, ferroelectric, and piezoelectric properties of mechano-chemically synthesized lead-free (1Àx)Ba 0.9 Sr 0.1 TiO 3 -(x)Ba 0.7 Ca 0.3 TiO 3 (x=0.0, 0.10, 0.20, 0.35, and 0.50) ceramics have been investigated. XRD patterns confirms the formation of tetragonal phase with P4mm space group. The results indicate a strong influence of BCT substitution on the structural and electrical properties of Ba 0.9 Sr 0.1 TiO 3 (BST) ceramic. BST-BCT ceramic for x=0.35 have shown high dielectric constant e m~2 1 800, high remnant polarization P r~1 0.16 lC/cm 2 , large piezoelectric charge constant D 33~2 93 pC/N, large piezoelectric voltage constant g 33~5 .80 mVÁm/N, and highest dielectric breakdown strength E bd~2 24 kV/cm among the five synthesized samples. The correlation between structural, dielectric, ferroelectric, and piezoelectric properties of the BST ceramic with increasing BCT content have been systematically described on the basis of domain wall motion and grain size effect.

Mechanochemical synthesis is a technology formed in the 1950s. By applying mechanical energy, mechanochemical synthesis stimulates chemical reactions, causing structural and phase changes and enabling difficult or otherwise impossible reactions to occur. Mechanochemical reactions are relatively safe, clean and efficient. At present, the synthesis of oxide ceramic materials by mechanochemical methods has attracted widespread attention. In the production of oxide ceramic materials, the characteristics of ceramic powder have a certain influence on the molding, sintering, microstructure, and mechanical properties of subsequent ceramics. In this paper, the research progress of mechanical chemistry in the synthesis of nanostructures and composite oxide ceramic powders is reviewed. The effects of process parameters such as ball milling time, speed, atmosphere, grinding media, additives, and ball‐to‐powder ratio on reaction kinetics, phase formation, and powder properties are summarized. In addition, challenges and opportunities for ceramic powder synthesis are also discussed.
