In this article, spinel ferrite CoFe2O4 and multi-walled carbon nanotubes (MWCNTs) composites are constructed by a facile one-step solvothermal method. The pure phase of particles is confirmed X-ray diffraction patterns. Microstructure analysis demonstrates that monodisperse microspheres wound MWCNTs. With the introduction CNTs, there significant enhancement in imaginary part permittivity (ε″) ...
Magnetoelectric (Sr0.5Ba0.5Nb2O6)1?x?(CoFe2O4)x (x = 0.2–0.6) composites were prepared by a one-pot soft-chemistry synthesis using PEG400. Calcining at 700 °C resulted in nanocrystalline composite powders (dcryst. 24–30 nm) which sintered between 1050 and 1200 to ceramic bodies with relative densities up 98%. SEM investigations confirm the formation of ceramics 0–3 connectivity variable grain s...
