Micro-structure and magnetic properties of annealed Fe-Co double-layer.

Structure and Magnetic Properties of Oxide Nanoparticles of Fe-Co-Ni Synthesized by Co-Precipitation Method

Oxide nanoparticles of Fe-Co-Ni were prepared in six different compositions by co-precipitation method. The as-synthesized nanoparticles were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron microscope (FESEM), Fourier Transform Infrared (FT-IR) and Vibrating Sample Magnetometer  (VSM). It was found that the nanoparticles had mean crystalline size of 30-55 nm and spher...

Effect of Cobalt Concentration on Structural and Magnetic Properties of Co-Fe Thin Films

Co-Fe films were electrodeposited on Cu substrate from electrolytes with different Co concentration  levels. X-ray diffraction (XRD) was used  to  investigate  the  films  crystal  structures. The  results  indicate that  if  the  Co  concentration  is  less  that  the  Fe  concentration,  the cubic  structure  appears  in  the  films, while  the  hexagonal  structure dominates when  the C...

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...
