Magnetic and Microwave Absorbing Properties of Ti and Co Substituted M-hexaferrites in Ka-band Frequencies (26.5¢?¬°40 GHz)

In this study, magnetic and microwave absorbing properties of M-hexaferrites have been investigated in Ka-band frequencies with the substitution of Ti<sup>+4</sup> and Co<sup>+2</sup> ions into Fe<sup>+3</sup> sites. The powders of composition BaFe<sub>12-2x</sub>Ti<sub>x</sub>Co<sub>x</sub>O<sub>19</sub> were prepared by calcining at 1250 ringC in air. Saturation magnetization and coercivity were measured using a vibration sample magnetometer.
