| 中文摘要 | the electronic structure of cacu3mn4o12 and lacu3mn4o12 was investigated using a full-potential linearized augmented plane wave method within the generalized gradient approximation (gga). the ferrimagnetic and ferromagnetic states in these two compounds were investigated and the calculated spin magnetic moments were found to be close to the available experimental values. calculations of spin polarization for these two oxides show that the ferrimagnetic configurations are the energetically favored ground state, which is consistent with experimental observation. the calculations predict that cacu3mn4o12 is a semiconductor and that lacu3mn4o12 is a half-metallic material. furthermore, the relevance of these different electronic structures to the magnetoresistance is discussed. |
