We investigated the opportunities for obtaining hexaferrites Pb 1− x La x Fe 12− x Zn x O 19 ( x = 0–1) from citrate–glycerin gel and showed that synthesis occurs via the formation of the Fe 3O 4 phase; products with a small amount of hematite impurity Fe 2O 3 can be obtained after firing at 800 to 900 °C with 0 ≤ x ≤ 0.5. If x > 0.5, perovskite-like LaFeO 3 is formed in samples, so that if x = 0.9–1, the synthesis products virtually do not contain phases with hexaferrite structures and represent a mixture of LaFeO 3, Fe 2O 3, and Fe 3O 4. Within the range of 0 ≤ x ≤ 0.5, the electrical and magnetic characteristics of hexaferrites Pb 1− x La x Fe 12− x Zn x O 19 are slightly dependent on x and have the following average values: A relative permittivity ε/ε 0 ~ 45, a dielectric loss tangent tan δ ~ 0.6, an electrical resistivity R ~ 10 9 Ohm cm, coercivity H c ~ 3 kOe, saturation magnetization M s ~ 50 emu/g, and remanent magnetization M r ~ 25 emu/g. The magnetoelectric (ME) ceramics 50 wt.% PZTNB-1 + 50 wt.% Pb 1− x La x Fe 12− x Zn x O 19 (PZTNB-1 is an industrial piezoelectric material based on lead titanate zirconate (PZT) do not contain impurity phases and have the following characteristics: Piezoelectric coefficients d 33 = 10–60 and −d 31 = 2–30 pC/N, piezoelectric voltage coefficients g 33 = 2–13 and −g 31 = 1–5 mV m/N, an electromechanical coupling coefficient K p = 0.03–0.13, magnetic parameters H c = 3–1 kOe, M s = 50–30, and M r = 25–12 emu/g. The maximum ME coupling coefficient ΔE/ΔH ~ 1.75 mV/(cm Oe) was achieved with x = 0.5.
