Abstract The simultaneous enhancement of magnetic and dielectric properties in nanomaterials is becoming increasingly important for achieving exceptional microwave absorption performance. However, the engineering strategies modulating electromagnetic responses remain challenging, underlying magnetic‐dielectric loss mechanisms are not yet fully understood. In this study, we constructed novel dual‐coupling networks through tightly packed Fe 3 O 4 @C spindles, which exhibit both dissipation effects. During spray‐drying process, vigorous self‐assembly facilitated formation hierarchical microspheres composed nanoscale core‐shell ferromagnetic units. Numerous heterogeneous interfaces abundant domains were produced these microspheres. integrated dielectric/magnetic coupling networks, formed by discontinuous carbon layers closely arranged contribute to strong intense interfacial polarization interactions. behind losses elucidated Lorentz electron holography micromagnetic simulations. Consequently, demonstrate excellent low‐frequency performance, an effective bandwidth 3.52 GHz, covering entire C‐band from 8 GHz. This study reveals that strategy synergistically enhancing improving performance nanomaterials. image
