Structure, magnetic and electrical transport properties of the perovskites La0.67−xEuxSr0.33MnO3

► La0.67−xEuxSr0.33MnO3 crystallize in the rhombohedral structure. ► The magnetization undergoes a strong decrease of TC. ► The electrical investigation shows a metallic-semiconductor transition. ► Metallic regime is emanated from the electron-(phonon, magnon) scattering processes. ► The electrical resistivity above TP is explained by Variable Range Hopping model.
