![عکس صفحه اول مقاله: Competition between quantum fluctuation and ferroelectric order in Eu1âxBaxTiO3 Competition between quantum fluctuation and ferroelectric order in Eu1âxBaxTiO3](/preview/png/5362219.png)
A series of polycrystalline Eu1âxBaxTiO3 (0.0 â¤Â x â¤Â 1.0) samples were synthesized through solid-state reaction method, and their microstructural, ferroelectric, dielectric, and phase transition properties are researched. We investigated the structural properties of Eu1âxBaxTiO3 system and revealed the structure transition from cubic perovskite to tetragonal perovskite with increasing x. More importantly, it is found that there exists strong quantum fluctuation (QF) in EuTiO3 and the ferroelectric state is built only at relatively high level Ba doping. Furthermore, quantum ferroelectric state (QFE) with broad scope is revealed for Eu1âxBaxTiO3 system through our ferroelectric and dielectric measurements.
⺠The quantum ferroelectric (QFE) state for Eu1âxBaxTiO3 has been revealed. ⺠The strong quantum fluctuation (QF) in EuTiO3 has been identified. ⺠It has been suggested that Eu1âxBaxTiO3 can be a substitute for the important perovskite oxide (Sr, Ba) TiO3.
