Microwave and electrical properties of Co-Ti substituted M-type Ba hexagonal ferrite
The microwave characteristics of Co2+ and Ti4+ ions substituted, BaCoxTixFe(12−2x)O19 (x = 0.1, 0.3, 0.5, 0.7, 0.9) ferrite have been studied as a function of thickness, frequency and substitution. The results depict reflection loss of − 31.94 dB at 10.47 GHz in x = 0.9. The highest static electrical current is observed at lower substitution. The model accompanying microwave absorption is used to evaluate microwave absorption characteristics. The electromagnetic and static electrical characteristics are improved with the substitution of Co2+ and Ti4+ ions. The compositions for possible electromagnetic applications are also explored.
