“…The compacts so prepared were subjected to final sintering at 1050oC for 24h in programmable furnace and slow cooled to room temperature to yield the final product. The details of the method of the preparation have been given in earlier publication (4). The Seebeck coefficients were measured by a differential method (5) from room temperature to well beyond the Curie temperature.…”

Hermoelectrical studies of Ni substituted Ni-Mg-Zn-Cu ferrites of various compositions were studied from room temperature to well beyond the Curie temperature by differential method. The series of samples were prepared by standard double sintering ceramic method. The Seebeck coefficient was measured as a function of temperature and found to be negative for all compositions showing that these ferrites are n-type semiconductors. The variation of thermoelectric power as a function temperature is discussed based on obtained results.

“…Among the EM wave absorbing materials, ferrite was most studied in experiments and applied in both military and civil fields because of its large saturation magnetization, anti-oxidation, and corrosion resistance [6][7][8][9]. In previous studies, among the spinel ferrites, LiZn-ferrite and NiZn-ferrite have been used in EM wave absorber materials in VHF and UHF bands [10][11][12][13][14][15]. In this study, as an absorbent material, ferrite composite was composed of lithium, nickel, and zinc.…”

This paper reports on a study of LiNiZn-ferrite composite as a radiation absorbent material (RAM). The electromagnetic (EM) wave absorbers are composed of an EM wave absorbing material and a polymeric binder. The surface morphology, chemical composition, weight percent of the ferrite composite of the toroid sample, magnetic properties, and return loss are investigated using field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), and network analyzer. For preparing the absorbing sheet, chlorinated polyethylene (CPE) is used as a polymeric binder. The EM wave absorption properties of the prepared samples were studied at 4 -8 GHz. We can confirm the effects of the thickness of the samples for absorption properties. An absorption bandwidth of more than a 10-dB return loss shifts toward a lower frequency range along with an increase in the thickness of the absorber.
