Co0.2Ni0.5Zn0.3EuxFe2-xO4 (CNZEFO) composites were synthesized by the conventional double sintering technique, where x = 0.00, 0.02, 0.04, and 0.08. Rietveld refined x-ray diffraction indicates spinel cubic structure (Fd-3 m space group) of samples. The XRD pattern also mentioned Fe2O3 secondary peak for 0.04 0.08 structural lattice constant was initially increased, but after that it decreased with Eu concentration. bulk density samples always lower than density, densities increased enhancement FTIR analysis confirmed metal–oxygen bonds in ferrite structure. FESEM micrographs provide average grain size samples, which varies between 105.1 nm 169.9 nm. EDX used to carry out compositional verification confirm elements present required ratios. Magnetic hysteresis loop measurements studied at room temperature, magnetization demonstrates decline substitution ions. addition concentration changed other fundamental properties ferrites, such as coercivity (Hc), retentivity (Mr), anisotropy (K), magnetic moment (nB). permeability show real decreasing frequency region further they became high higher region. loss tangent (tanδM) dielectric (tanδD) reduced concentration, doped quality factor pure sample. resistivity impedance noticed content Co0.3Ni0.2Zn0.5Fe2O4 These europium cobalt–nickel-zinc ferrites may be strong candidates potential applications.
