ABSTRACT A solid solution of the composition TlFe0.975Ga0.025S2 was obtained by direct synthesis from the initial elements. The thermo-emf and electrical conductivity of the obtained solid solution have been studied in the temperature range 77-350K. It was found that, depending on the method for preparing a 2.5% Ga solid solution sample, the Néel temperature changes from TN = 150 K in a single crystal to TN = 180.5 K in pressed samples. The thermo-emf of the sample is observed to pass from p-type to n-type in a single crystal at TN = 150 K and in pressed samples at 255 K and 284 K, respectively. Keywords: solid solution, magnetic phase transition, additive, thermoelectric motive force.
