Employing the Microemulsion Synthesis Technique to Investigate the Structural and Magnetic Properties of Multicomponent Ferrite Nanoparticles

Abstract

CoFe₂O₄, ZnFe₂O₄, NiFe₂O₄, Co_0.5Ni_0.5Fe₂O₄, Ni_0.5Zn_0.5Fe₂O₄, and Co_0.5Zn_0.5Fe₂O₄ are among the multicomponent ferrite nanoparticles that are created using the reverse microemulsion technique and a mixed surfactant. These nanoparticles are thoroughly characterized using techniques such as vibrating sample magnetometer (VSM), energy dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD). All the nanoparticles display a cubic spinel crystal structure, according to the X-ray investigation. As the concentration of zinc increases, there is a noticeable rise in the lattice constant because the size of Zn+2 is more than Co+2. This study also investigates the relationship between the magnetic characteristics of nanocrystals and their matching size, composition, and features.
