                         synthesis, calcination at 1000 °C and sintering at 1250 °C in air 
                         atmosphere. The microstructure and phases of the sintered sample 
                         were analysed by scanning electron microscopy and X-ray 
                         diffraction, respectively. The magnetic properties of the ferrite 
                         were evaluated by magnetization and magnetostriction measurements. 
                         The complex magnetic permeability and complex permittivity were 
                         also measured between 1 MHz-12 GHz and the reflection loss (RL) 
                         was calculated in the 100 MHz-12 GHz frequency range. The results 
                         show that the ferrite sample presents magnetostrictive behaviour 
                         and a saturation magnetization of 71 Am2/kg. Complex permittivity 
                         measurements indicate that the material has dielectric behaviour 
                         in the whole frequency range studied, with \ε\′ 
                         varying between 7-40, and magnetic behaviour in frequencies 
                         between 1 MHz-5 GHz. The minimum RL was found at frequencies 
                         between 2.4-3.3 GHz and the calculated RL value for a thickness of 
                         3 mm was lower than \−10 dB in frequencies between 2.3-7.3 
                         GHz. These results indicate potential application as microwave 
                         absorber in the S band.",
