Room-temperature magnetoelectric coupling in single-phase BaTiO3-BiFeO3 system
In this paper, single-phase multiferroic ceramics of (1 x) BaTiO3 x BiFeO3 (BT x BFO) were synthesized by solid-solution method in the wide range of material composition (x1⁄4 0.025 – 1.0). The changes in crystal structure were confirmed via X-ray diffractions (XRD) and atomic pair distribution functions (PDFs). The room-temperature ME coupling was found to exhibit significant magnitude in the ...
متن کاملCompositional dependence of hyperfi ne interactions and magnetoelectric coupling in (BiFeO3)x-(BaTiO3)1–x solid solutions
The promise of coupling between magnetization and electric polarization and the potential to manipulate one through the other has become in recent years a driving force for many experimental works on multiferroic materials. The ultimate goal of these studies would be a single-phase material exhibiting a strong coupling between inherent ferromagnetic and ferroelectric ordering at room temperatur...

15 صفحه اولCombined effects of PEGylation and particle size on uptake of PLGA particles by macrophage cells
Objective:At the present study, relationship between phagocytosis of PLGA particles and combined effects of particle size and surface PEGylation was investigated. Materials and Methods:Microspheres and nanospheres (3500 nm and 700 nm) were prepared from three types of PLGA polymers (non-PEGylated and PEGylation percents of 9% and 15%). These particles were prepared by solvent evaporation metho...
متن کاملMelting of Bi sublattice in nanosized BiFeO3 Perovskite by resonant X-ray diffraction.
Free-standing BiFeO3 perovskite particles with a size ranging from polycrystalline bulk down to 5 nm have been studied by high-energy resonant (Bi K edge) x-ray diffraction coupled to differential atomic pair distribution function analysis. Nanosized BiFeO3 particles are found to exhibit extra, i.e., beyond the usual thermal, structural disorder that increases progressively with diminishing the...
