Magnetoresistive properties of Ni-doped La_(0.7)Sr_(0.3)MnO_3 manganites
|
摘要
La_(0.7)Sr_(0.3)Mn_(1-x)Ni_xO_3(x = 0, 0.025, 0.050 and 0.075) ceramics were prepared by the conventional solid-state reaction method. The partial substitution of Mn by Ni~(2+) leads to a decrease in cell volume as well as a structural transition from the rhombohedral to the orthorhombic structure. Ni~(2+) doping increases the electrical resistivity, decreases the semiconductor–metal transition temperature(Tms) and relatively enhances the room temperature magnetoresistance(MR), especially in x = 0.025 and around Tms. With respect to conduction mechanism, the small polaron hopping(SPH) and the variable range hopping(VRH) models were used to examine conduction in the semiconducting region.
