　　讲座摘要：
　　The coexistence of superconductivity and ferromagnetism in nanograins have been ivestigated via exact solution. Various phase diagrams have been obtained,which show the competitions and compromises between superconducting correlations and various orgins of spin polarizations, including spin exchange, magnetic field and asymmetry of bandwidths. Some mechanism behind the coexistence is also clarified. These systemic studies that pointed out the possibility for the coexistence in grain systems was in advance of the experimental finding of the coexistence of ferromagnetism and superconductivity in Sn nanoparticles.
