Effect of Zn-substitution on magnetic structure of cobalt ferrite nanoparticles

This study investigates the effects of Zn substitution on the magnetic properties of similar to 5 nm cobalt ferrite nanoparticles (ZnxCo(1-x)Fe(2)O(4), where x = 0, 0.13, 0.34, and 0.55), demonstrating that Zn substitution induces complex changes in spin canting and prompts a redistribution of cations among the sublattices. We reconstructed the magnetic structure of these spinel ferrites by integrating the classical two-sublattice N & eacute;el model of ferrimagnetism with the data obtained from Fe-57 M & ouml;ssbauer spectrometry. Consequently, this research provides a comprehensive understanding of how Zn substitution tunes the magnetic properties of CoFe(2)O4 nanoparticles, offering valuable insights into the development of magnetic materials with tailored properties for various applications.
