Enhancement the physical properties of V2O5/Ni0.1Fe2.9O4 nanocomposite

Abstract

AbstractNanocomposite containing vanadium oxide (V2O5) and magnetite (Fe3O4) doped with nickel (Ni) ion were synthesized according to the formula of Ni0.1Fe2.9O4 /V2O5. The obtained composition was characterized by XRD, FTIR, FESEM. The FESEM micrograph shows that the existence of two different phases related to V2O5 and Ni-Magnetite. Moreover,the roughness parameters have values of 281, 85 and 385nm for roughness average Ra, root mean square roughness Rq, Maximum height of roughness RT respectively. Moreover, the magnetic behavior of the sample was studied, and we found that by adding V2O5 to Ni dopped magnetite, the curie temperature value was lowered from 750 oC to 625 oC. The activation energy was calculated and found to be 0.22 eV and 0.08 eV for 1000 Hz and 3MHz respectively.
