| Summary: | <p>Electrical transport properties of the R<sub>3</sub>Ag<sub>4</sub>Sn<sub>4</sub> (R = Gd, Tb, Dy, Ho) intermetallics crystallized in the orthorhombic Gd<sub>3</sub>Cu<sub>4</sub>Ge<sub>4</sub> structure type (space group <em>Immm</em>) were studied in the temperature interval 11-300 K. Measurements of the temperature dependencies of electrical resistivity (<em>r</em>(<em>T</em>)) showed that all the studied compounds are characterized by metallic type of conductivity. The slope change of the resistivity at low temperature part of <em>r</em>(<em>T</em>) dependencies for Gd<sub>3</sub>Ag<sub>4</sub>Sn<sub>4</sub>, Tb<sub>3</sub>Ag<sub>4</sub>Sn<sub>4</sub> and Dy<sub>3</sub>Ag<sub>4</sub>Sn<sub>4</sub> compounds is connected with their magnetic ordering. Change of the resistivity caused by magnetic ordering was not observed for the Ho<sub>3</sub>Ag<sub>4</sub>Sn<sub>4</sub> compound in the studied temperature interval. Relation between magnetic and electric properties of the investigated R<sub>3</sub>Ag<sub>4</sub>Sn<sub>4</sub> compounds was analyzed.</p> |
