The samples of homogeneous (x = 0; 0.1; 0.2) and multilayer ceramics with compositional gradient (х = 0.2 → 0.1 → 0 → 0.1 → 0.2) based on solid solutions of nickel – zinc ferrites (Ni1–xZnx) Fe2O4 have been prepared by thick-film technology. The graded samples had smooth inhomogeneous distribution of chemical elements (Zn, Ni) throughout the thickness after sintering by the two-stage mode. The longitudinal (αE33) and transverse (αE31) magnetoelectric effects in bilayer PZT – nickel – zinc ferrite composites were studied. Magnetoelectric coefficients were not significant in the absence of an external constant magnetic field. The maximum value of the longitudinal magnetoelectric coefficient in composites with graded magnetic phase was almost two times higher than the value of αE33 in homogeneous structures.

Magnetic Hysteresis Loops

The samples of homogeneous (x = 0; 0.1; 0.2) and multilayer ceramics with “oncoming” compositional gradient (x = 0.2→0→0.2) based on solid solutions of nickel – zinc ferrites (Ni1–xZnx) Fe2O4 have been prepared by thick-film technology. It was possible to ensure the synthesis of ceramics and to maintain inhomogeneous distribution of chemical elements throughout the thickness of the graded samples using the two-stage mode of heat treatment. Microstructure and crystal structure of the materials are studied. It is shown that the volume of the unit cell increases with increasing zinc content, while the grain size does not change significantly. The features of the magnetization of multilayer structures were investigated for two variants of application of external magnetic field (parallel and perpendicular to the sample plane). The resulting hysteresis loop for multilayer graded sample can be obtained by “summing up” the loops of homogeneous layers of the structure. No internal fields leading to a shift and distortion of the magnetic hysteresis loops were detected.
