In this study, by substituting V with Nb, La2NbMnO6 is investigated using the density functional theory. The calculated results indicate that La2 NbMnO6 is also ferrimagnetic and exhibits the half metallic properties due to the strong electron correlation of Mn. The valence states of Nb and Mn are assigned to be 4-4 and +2 in La2NbMn06, respectively, which are different from V3+/Mn3+ in La2 VMnO6.展开更多
