The original technology for the synthesis of nanosized powders with a particle size of 30-150 nm and dense ceramics based on them have been developed. Theoretical and experimental studies of the phase diagrams of ferroelectric, magnetic and magnetoelectric properties of the above solid solutions have been carried out. For the compositions [(PbMg1/3Nb2/3O3)0.7(PbTiO0.3)] 1-х(PbFe1/2Ta1/2O3)x, x = 0.4 and 0.5, the existence of a paramagnetic effect was observed, which at room temperature three orders of magnitude larger than the widely known single-phase magnetoelectric materials in the world. The physical mechanism of such a giant magnetoelectric effect is developed. It is shown that it is related to the coexistence at room temperature of the superparamagnetic and ferroelectric phases.
