New decisions for tensors of effective pyroektromagnetic properties of piezoactive composites on the basis of the solution of the connected boundary volume problem of electromagnetothermoelasticity are received. Numerical calculation and the analysis of influence of Maxwell–Wagner relaxation, value of filling and form of inclusions on the real and imaginary parts of effective pyromagnetic coefficients of an electromagnetic titanate barium/ferrite with ellipsoidal ferrite inclusions, layers and fibers in a variation temperature field are carried out. The effect of emergence in a composite of the pyromagnetic coherence which is absent at its phases, and significant increase in effective longitudinal pyromagnetic coefficient for a composite with the spherical and poorly extended ellipsoidal ferrite inclusions in barium titanate, especially in the high-frequency range, in comparison with similar coefficient for unidirectional fibrous or layered composites is revealed.
Keywords: piezocomposite, pyromagnetic effect, Maxwell–Wagner relaxation, effective properties.
