Abstract

Highlights: [•] Effect of Mn-site doping by Ru has been studied in La1.24Sr1.76Mn2-y Ru y O7. [•] Electrical resistance, magnetoresistance and magnetic properties were measured. [•] Ru substitution enhances the ferromagnetism and metallicity. [•] Results were interpreted by the ferromagnetically coupled Ru with Mn ions in Mn–O–Ru network. [ABSTRACT FROM AUTHOR]
