Abstract

In this work, the NiFe₂O₄–reduced graphene oxide (NiFe₂O₄–rGO) was achieved via a one-step hydrothermal method. The microstructure, permittivity and permeability and electromagnetic attenuation properties of NiFe₂O₄–rGO are investigated. The minimum reflection loss reaches −46.8 dB at d = 4.8 mm. The introduction of NiFe₂O₄ nanocrystals enhances electromagnetic attenuation due to the synergetic effect of dielectric and magnetic loss as well as the enhanced exchange resonance. It is believed that the deposition of magnetic nanocrystals is a way to generate light-weight and high-efficient microwave absorbers. The NiFe₂O₄–rGO is a promising candidate for electromagnetic attenuation in various fields.
