Abstract:
Solid solutions Bi$_{2}$Te$_{3}$-Sb$_{2}$Te$_{3}$ continue to be the subject of numerous and versatile experimental studies due to their practical importance for thermoelectric materials science. In this regard, the problem of studying the regularities of changes in the state of the electronic system of these semiconductors from composition and temperature remains urgent. This paper presents the results of studying the temperature dependences of the magnetic susceptibility of Bi$_{2}$Te$_{3}$-Sb$_{2}$Te$_{3}$ crystals containing 10, 25, 40, 50, 60 mol.% Sb$_2$Te$_3$. The correlation of the behavior of the temperature dependences of the magnetic susceptibility and electrical conductivity is analyzed.
Keywords:
magnetic susceptibility, diamagnetic susceptibility, temperature dependence of electrical conductivity.
