Resumo
The patterns of effect of the ferromagnetic filler content on the features in the microstructure of “Ni core–shell NiTe2” inclusions, changes in the Seebeck coefficient and electron concentration in samples of the Bi2Te3 (matrix) + xNi (filler) composites with x = 0.00; 0.50; 0.85; 1.25 and 1.50 wt % have been found. It is shown that the Seebeck coefficient in the composites x = 0.50 and 0.85 exceeds the calculated values, which may be due to additional scattering of electrons by the magnetic moments of inclusion atoms.
