The study of the temperature dependences of the electrical resistance R and thermal EMF S of a single crystal of samarium monosulfide SmS in two cycles in the range 320-800 K. It has been established that cyclic temperature action has a significant effect on the processes of electrical transfer in the test sample, which is found in hysteresis phenomena on the dependences of ln[R(103/T)] and S(T), as well as in changes in the behavior of the latter in the high-temperature region, both due to rearrangement of the impurity and exciton spectra, and the participation of in electronic transport the 5d-subzone of the SmS conduction band. Keywords: samarium monosulfide, thermal EMF, temperature cycling, electrical resistance.
