The College of Science, University of Diyala discussed a Ph.D. thesis on improving the properties of modern ferrite-based antennas for wireless applications by the postgraduate student, Ms. Saja Bassem Mohammed.
The thesis aimed at studying the electromagnetic properties of materials composed of ferrite nanoparticles embedded in polyvinyl alcohol arrays.
The thesis included an analysis of the structure, shape, and magnetic properties of the nanoparticles using X-ray diffraction, scanning electron microscopy and a vibrating sample magnetometer.
The thesis demonstrated the possibility of obtaining the ferrite phase at the spontaneous combustion temperature, as well as preparing samples contained a spinel structure and that the nanoparticles exhibited magnetic behavior combining ferromagnetic and paramagnetic properties at 1200°C, compared to the ungalvanized sample.
