Abstract

Hierarchical Fe₃O₄ architectures assembled with porous nanoplates (p-Fe₃O₄) were synthesized. Due to the strong shape anisotropy of the nanoplates, the p-Fe₃O₄ exhibits increased microwave resonance towards high frequency range. The improved microwave absorption properties of the p-Fe₃O₄, including dielectric loss and magnetic loss, are attributed to the enhanced electric polarization and interfacial polarization induced by oxygen vacancies and high surface area.
