Ferrite System for Application at Lower Microwave Frequencies

Abstract

The ferrimagnetic system $(\mathrm{LiFe}{)}_{\text{1−0.5a−0.5x}}{\mathrm{Zn}}_x{\mathrm{Fe}}_{\text{2a−y}}{\mathrm{Ti}}_{\text{1−a}}{\mathrm{Al}}_y{\mathrm{O}}_4$ is found to form a single-phase solid solution for the investigated values $\text{0≤a≤l}$ , $\text{0≤x≤0.1}$ , and $\text{0≤y≤0.l5}$ . For approximately $\text{0.2≤a≤0.4}$ , the system exhibits relatively high Curie temperatures and properties compatible with the requirements of ferrites for utilization in nonresonant devices at the lower microwave frequencies.
