Abstract
The influence of γ-quantum on the magnetoelectric properties of Bi0.85Sb0.15 (0.001≤x≥0.05) thermoelectrics doped with lead atoms at ∼77÷300K and magnetic field induction up to 1.0 Tesla has been studied. It was found that at low doses of gamma irradiation of the Bi0.85Sb0.15 solid solution, point defects are formed, which lead to an increase in the concentration of free electrons n, specific electrical conductivity σ and a decrease in the absolute value of the thermo EMF coefficients α and RH. As the dose of γ-quanta increases in the process of subsequent restructuring, point defects accumulate, i.e. accumulation of point defects, which leads to a decrease in the concentration of current carriers and a corresponding change in σ, α. and RH.
