摘要：

The electrical resistivity of the SmxMn1-xS (0.15=x=0.25) solid solutions in the temperature range of 80-300?K was measured. Minimum and maximum in the temperature dependence of the resistivity were found, respectively, at T=220K for x=0.15 and at T=100K for x=0.2 compounds. This behavior is explained from the result of the mobility-edge movement, the disorder being due to elastic deformation and spin density fluctuations with short-range order. Metalsemiconductor phase transition versus concentration at xc=0.25 is observed. Resistivity is described by scattering electrons with acoustic phonon mode and with localized manganese spin. From the thermal expansion coefficient the compression of the lattice below the Neel temperature for Sm0.2Mn0.8S is found.
