1999年9月2日 · A single phase PMN powder of perovskite structure has, for the first time, been successfully prepared via a novel mechanical activation route. This is a revolutionized step forward in fabricating PMN and PMN-based relaxor ferroelectrics, by skipping the multiple steps of calcination when constituent oxides are used as the starting materials.

2024年1月22日 · Sintered pellets were polished and characterized for phase and crystal structure using X-ray diffraction (XRD) to confirm single-phase formation of PMN–PT ceramics. Dielectric and electromechanical properties were measured using a …

2011年3月1日 · Complex perovskite structure relaxor ferroelectric single crystals, lead magnesium niobate–lead titanate (PMN–PT) near its morphotropic phase boundary (MPB), have attracted much attention owing to its excellent dielectric and piezoelectric properties, which may be applied in various kinds of devices, such as sonar transducers, medical ...

2009年9月1日 · Single-phase perovskite 0.65PMN–0.35PT nanopowders were synthesized at low temperature by the auto-combustion method. PMN–PT powder with 1 mol% of excess Pb(NO 3) 2 was prepared from the constituent nitrates and alkoxide materials. Perovskite PMN–PT powders without any pyrochlore phase were obtained after heat treatment at 850 °C.

Single crystals based on solid solutions of lead-magnesium-niobate (PMN) and lead titanate (PT) have emerged as highly promising multifunctional systems combining piezoelectric, pyroelectric, and...

We have synthesized and were performed a comparison of structures and optical properties between relaxor ferroelectric PMN–PT and PMN–PZT nanopowders. A gel-combustion method has been used to synthesize PMN–PT and PMN–PZT nanocrystalline with …

2024年4月24日 · In this study, we grew a single-crystal (110)-oriented SMO thin film on a (La 0.7 Sr 0.3 )MnO 3 (LSMO)-buffered PMN-PT substrate using pulsed laser deposition (PLD) to investigate the effect of strain and oxygen vacancies on the structural and ferroelectric properties.

Single-phase perovskite 0.65PMN–0.35PT nanopowders were synthesized at low temperature by the auto-combustion method. PMN–PT powder with 1 mol% of excess Pb(NO3)2 was prepared from the constituent nitrates and alkoxide materials. Perovskite PMN–PT powders without any pyrochlore phase were obtained after heat treatment at 850 8C.

In this paper, it was found that the domain configuration of PMN-PT single crystals was influenced by machining and electric process, such as cutting, grinding, polishing, and electrical field...

2023年2月15日 · Lead-based relaxor ferroelectric perovskite oxides, exemplified by the (1–x)Pb (Mg 1/3 Nb 2/3)O 3 –xPbTiO 3 (PMN-PT) solid solution, are a group of multifunctional materials with unique...
