THERMOELECTRIC PROPERTIES IN THE CATION-SUBSTITUTED COMPOUNDS Re<sub>X</sub>Mn<sub>1-X</sub>S (Re = Gd, Sm)
This paper presents the results of a study of the transport properties of cation-substituted sulfides ReXMn1-XS (Re = Gd, Sm) with FCC NaCl type in the temperature range 77-1200 K. The temperature dependence on Seebeck coefficient for systems with gadolinium and with samarium reveals the negative values of thermoelectric power in all range of temperatures with increasing concentration X.
