Electrical resistivity and Curie temperature studies on (Y1−xGdx)(Fe0.7Co0.3)2 intermetallics

► The contributions to total resistivity were separated for the (Y1−xGdx)(Fe0.7Co0.3)2. ► The Debye temperatures were determined from measured resistivity. ► The Curie temperatures increases linearly with de Gennes factor. ► The magnetic ordering temperatures increases linearly with square of hyperfine fields.
