Cobalt Ferrite/Barium Titanate Core/Shell Nanoparticles 117 for 12 hours. This treatment causes the media to repeatedly impact on the coarse and agglomerated particles of cobalt ferrite producing de-agglomerated fine particles coated by the surfactant. The ferrofluid was then separated by centrifugation at about 7000 rpm,

This technique can selectively probe the surface of the NCs and was used to study the ferroelectric-to-paraelectric phase transition of barium titanate (BTO) nanocubes in three size regimes of 16 ± 4, 47 ± 11, and 220 ± 140 nm. Temperature-dependent Raman spectroscopy was also applied to probe the whole volume of the NCs.
ferrite and barium titanate starting phase, as well as for the composites with 20 and 40 wt.% of nickel ferrite. Barium titanate has narrow diffraction peaks corresponding its 2 µm average size, while cobalt ferrite synthesized by chemical coprecipitation has wide peaks due to its nanometric crystal size. On the other hand, the x-ray
Magneto-dielectric effects in self-assembled core-shell nanoparticles of nickel ferrite (NFO) and barium titanate (BTO) have been investigated in the millimeter wave frequencies. The core-shell nano-composites were synthesized by coating 100 nm nickel ferrite and 50 nm barium titanate nanoparticles with complementary coupling groups and allowing them to self-assemble in the .
