Abstract

In this work, the spinal ferrite 2 4 NiFe O has been prepared. The
prepared ferrite material was used as radar absorbing material ( RAM ).
The absorption for microwaves was investigated via the use of network
analyzer method. The values of reflectivity and absorption were
calculated as a function of frequency at X -band with an (0.0225)GHz
increase. The relationship between reflectivity and absorption was plotted
as a function of frequency for all prepared samples and their sintering
temperature: (1050, 1100, 1150) 0C. The results were appearance of a
numbers of resonance peaks at X -band frequencies. Further, it was
shown that the highest values of the absorption and less values of the
reflectivity were reached at the sintering temperature 1150 0C. Also,
testing of X  ray diffraction ( XRD) was made for this ferrite, where the
results showed compatibility with standard results except for secondary
phases with the ferrite samples.
