Theoretical Model and Numerical Calculation for a Organic Ferromagnet

用一个理论模型描述共轭有机铁磁体，考虑了π电子的巡游性和电子-电子关联作用．在平均场理论和Hartree近似下，建立了一组自洽方程计算。电子能级结构。结果表明能级相对自旋是分裂的，系统基态是一个稳定的铁磁态。

A theoretical model is proposed to describe the organic ferromagnets. Concerning the itineracyof x electrons and electron-electron correlation in a one-dimensional system, and within the meanfield theoryand Hartree approximation, this paper presents a set ofselfconsistent iterative equations to study the energylevel 0f' electrons in the organic materials. The results of calculations show that the energy levels of rr electronssplit off with respect t0 different spins, the ground state of the system is a stable ferromagnetic state.
