Abstract
The results of studies of the properties of co-deposition of magnetic nanoparticles (MNPs) of Co1-xZnxFe2O4 spinel ferrites synthesized (at x=0.0; 0.1; 0.2; 0.4; 0.6) in order to create magnetic particles for biomedicine. X-ray diffraction (RD), raman scattering of light, magnetic measurements and Mossbauer spectroscopy (MS) were used to study the obtained Co1-xZnxFe2O4 MNPs. It was found that the synthesized MNCs CoxZn1-xFe2O4 are single-phase. According to the results of RD measurements, it was found that the average sizes of crystallites are 13 nm for CoFe2O4 (x=0) and, with an increase in the Zn concentration, they decrease to 7 nm for Co1-xZnxFe2O4 (x=0.6), which is consistent with the Mössbauer data, which showed that the sizes of crystallites vary from 14 to 8 nm. In the raman spectra of the Co1-xZnxFe2O4 MNF in the region of ~620 cm-1, splitting of the A1g line is observed, indicating that the studied particles have an inverse spinel structure.
