Multimechanism Decoupling for Low‐Frequency Microwave Absorption Hierarchical Fe‐Doped Co Magnetic Microchains

Abstract The rapid development of military and civilian electronic communication technology poses a severe challenge to controlling electromagnetic radiation pollution in the low‐frequency microwave band. This study introduces a novel one‐step feeding self‐assembly and ripening strategy to synthesize 1D@2D magnetic microchains (Co@Fe x Co 1‐ x OOH, CFC). The experimental and simulation results show that increasing the flux length and ordered orientation is very important to improve the absorption performance of 1D magnetic absorber. The CFC‐LC‐E (long‐chain CFC aligned along the electric field direction) prepared based on the above characteristics successfully achieves a high‐performance microwave absorption…
