| 中文摘要 | On the basis of the Hubbard model, we present the formulation of antiferromagnetism (AF) in electron-doped cuprates using the fluctuation-exchange approach. Taking into account the spin fluctuations in combination with the impurity scattering effect due to the randomly distributed dopant atoms, we investigate the magnetic properties of the system. It is shown that the antiferromagnetic transition temperature, the onset temperature of the pseudogap formation, the single-particle spectral density, and the staggered magnetization obtained by the present approach are in very good agreement with the experimental results. The distribution function in momentum space at very low temperature is observed to differ significantly from that of the Fermi liquid. Also, we find a zero-energy peak in the density of states (DOS) of the antiferromagnetic phase. This DOS peak is sharp in the low-doping regime and disappears near optimal doping where the AF order becomes weak. |
