The influence of doping level x on cohesive energy and Mn4+ ion content of La0.7Sr0.3-xAgxMnO3 manganites

摘要：

Based on the thermal equilibrium theory of crystal defects, the phenomenon of that unit cell volume of La0.7Sr0.3-xAgxMnO3 perovskite manganites increases with increasing the doping level x, has been explained through computating cohesive energy of the system, as well as the phenomenon that the Curie temperature Tc decreases with the doping x increase.

关键词： Cohesive energy Double exchange mechanism Perovskite Vacancy
