One-dimensional multiferroic bismuth ferrite fibers obtained by electrospinning techniques.
We report the fabrication of novel multiferroic nanostructured bismuth ferrite (BiFeO(3)) fibers using the sol-gel based electrospinning technique. Phase pure BiFeO(3) fibers were prepared by thermally annealing the electrospun BiFeO(3)/polyvinylpyrrolidone composite fibers in air for 1 h at 600 °C. The x-ray diffraction pattern of the fibers (BiFeO(3)) obtained showed that their crystalline st...
متن کاملElectrical control of multiferroic orderings in mixed-phase BiFeO₃ films.
Recent advances in thin-fi lm engineering leads to a new type of mixed-phase system in BiFeO 3 (BFO) epitaxial fi lms driven by substrate strain. [ 1 ] Single-phase multiferroic BFO had attracted great interests due to its robust ferroelectric and antiferromagnetic orderings at room temperatures. [ 2–11 ] Under a strong compressive strain ( > 4%), the stable crystal structure of BFO transformed...
متن کاملSynthesis and characterization of multiferroic BiFeO3 nanotubes.
Multiferroic bismuth ferrite (BiFeO(3)) nanotubes have been synthesized using a modified template methodology and characterized by a number of techniques, including XRD, SEM, TEM, HRTEM as well as EDX and SAED.
متن کاملInfluence of strain and oxygen vacancies on the magnetoelectric properties of multiferroic bismuth ferrite
The dependencies on strain and oxygen vacancies of the ferroelectric polarization and the weak ferromagnetic magnetization in the multiferroic material bismuth ferrite, BiFeO3, are investigated using first principles density functional theory calculations. The electric polarization is found to be rather independent of strain, in striking contrast to most conventional perovskite ferroelectrics. ...
متن کاملSuperior electro-optic response in multiferroic bismuth ferrite nanoparticle doped nematic liquid crystal device
A superior electro-optic (E-O) response has been achieved when multiferroic bismuth ferrite (BiFeO3/BFO) nanoparticles (NPs) were doped in nematic liquid crystal (NLC) host E7 and the LC device was addressed in the large signal regime by an amplitude modulated square wave signal at the frequency of 100 Hz. The optimized concentration of BFO is 0.15 wt%, and the corresponding total optical respo...
