Abstract

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.
