Dense lithium ferrite ceramic bodies prepared by hot‐pressing exhibited rectangular hysteresis loops. A number of physical properties of technical interest were evaluated and results given. These include initial permeability, dc resistivity, resonance Une width, g eff factor, and saturation magnetization. The effect of 3–1 octahedral site ordering is discussed. Investigation was extended to the preparation of solid solutions of lithium ferrite and zinc ferrite (Lio. 0.5 Feo. 0.5 ) 1‐x Zn x ‐Fe 2 O 4 , where 0 ≤ x ≤ 0.7. Methods of separate control of remanent induction, B r , and coercive force, H c , are described.
