Co-doped MnFe2O4 nanoparticles: magnetic anisotropy and interparticle interactions

Spherical magnetic nanoparticles: magnetic structure and interparticle interaction

The interaction between spherical magnetic nanoparticles is investigated from micromagnetic simulations and ananlysed in terms of the leading dipolar interaction energy between magnetic dipoles. We focus mainly on the case where the particles present a vortex structure. In a first step the local magnetic structure in the isolated particle is revisited. For particles bearing a uniaxial magnetocr...

Synthesis and Investigation of Optical and Magnetic Properties of Co-Doped effect on Zinc Oxide Nanoparticles

In this study, the effect of simultaneous doping of magnesium, calcium, and copper ions on the properties of zinc oxide doped with cobalt was investigated. The sol-gel method has been used for the synthesis of nanoparticles. The structural and optical properties of the synthesized nanoparticles were investigated using X-ray diffraction (XRD), infrared spectroscopy (FTIR), and DRS spectroscopy. ...

Magnetic Properties of Fe Doped, Co Doped, and Fe+Co Co-Doped ZnO

The structural, electronic and magnetic properties of Zn0.95Co0.05O, Zn0.95Fe0.05O and Zn0.90Fe0.05Co0.05O nanoparticles prepared by a sol-gel method are presented and discussed. Xray diffraction and optical analysis indicated that high spin Co ions substitute for the Zn ions in tetrahedral sites. Fe Mössbauer spectroscopy showed the presence of isolated paramagnetic Fe ions in both Fe doped an...
