摘要:A series of Cr-doped multiferroelectric FeBiO3 nanoparticles were synthesized via a facile sol gel method. The resultant Cr-doped FeBiO3 was characterized by means of different techniques, such as scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), transmission electron microscopy (TEM), X-ray powder diffraction (XRD) and electrorheological (ER) tests. Under an external electric field, electrorheological properties of the suspension containing such Cr-doped and undoped FeBiO3 particles were investigated by steady shear experiments. It was found that the suspension of Cr-doped FeBiO3 particles possesses a better ER effect than that of pure FeBiO3 particles. Furthermore, different Cr-doped concentration plays an important role on the ER behavior. Combining the dielectric analysis, the enhanced ER effect of Cr-doped FeBiO3 suspension can be attributed to the improved interfacial polarization. (C) 2014 Elsevier B.V. All rights reserved.
