Surface cladding of Magnesium ferrite (MgFe2O4) was found to be helpful for effectively decreasing the permittivity of Fe flakes. So the electromagnetic impedance matching was improved, resulting in a good microwave absorption. Careful characterizations showed that the giant decreases of permittivity were ascribed to the high resistivity of surface due to the MgFe2O4 cladding. A high frequency microwave absorption property with thin absorber thickness was obtained for the Fe flakes with 10 wt% MgFe2O4.
► The electromagnetic wave absorption of Fe flakes was improved by MgFe2O4 cladding. ► The decreased permittivity causes a better electromagnetic impedance matching. ► A high frequency microwave absorption property was obtained for the Fe flakes.
