Abstract: The severely degraded permeability and the increased magnetic loss at GHz frequencies, induced by domain wall resonance, pose a critical barrier to the integration of magnetic materials into advanced high-frequency devices. To overcome this, we propose a magnetic domain engineering strategy that enables precise and controllable modulation of magnetic domain structures in ferrite composites, implemented by simultaneously introducing strong shape anisotropy and suppressing interparticle exchange coupling. This strategy not only suppresses the magnetic loss introduced by domain wall resonance, but also effectively balances the contributions of domain wall motion and magnetic moment precession to the dynamic magnetization process, thereby sustaining a relatively high permeability. The spinel ferrite-based composites produced using this strategy achieve a combination of high permeability (μ′ = 2.0) and low magnetic loss (tan δ μ = 0.05) in the frequency band up to 3 GHz, representing a significant advance toward practical GHz range functionality. In addition, when employed as a substrate in a patch antenna, the composites enable a 64% size reduction compared to commercial materials, underscoring their feasibility and promise for antenna miniaturization. This work proposes an alternative strategy for magnetic optimization in ferrite composites and widens their application to high-frequency devices. [ABSTRACT FROM AUTHOR]
