The spinel ferrite materials with rare-earth oxides are considered to be the major contenders to address numerous critical issues in various scientific and technological fields. Herein, ZnYb x Fe2- x O4 ( x = 0.00, 0.025, 0.05, 0.075, 0.1) spinel ferrite samples were prepared and investigated in terms of structural, magnetic, vibrational and dielectric for microwave and antenna applications. A structurally stable rare earth Yb doped spinel ferrite leads to enhances the defect polarization and interfacial polarization, resulting in improved magnetic and dielectric properties. ZnYb x Fe2- x O4 at x = 0.075 exhibited the maximum reflection loss (RL) of −28.86 dB, demonstrating markedly superior microwave attenuation relative to the pristine ZnFe2O4. The M–H hysteresis loop reveals soft magnetic pseudo-single-domain behavior, with coercivity values of 15.71–24.41 Oe and saturation magnetization values of 53.02–64.61 emu/g. These results provide a framework for tailoring rare earth Yb-doped oxides to microwave devices and next-generation antenna systems. © 2026 Elsevier B.V.
