摘要：
Cu-induced spin polarization in tris(8-hydroxyquinoline) aluminum (Alq(3)) has been studied by first-principles calculation. The entanglement between an electron transfer from Cu to Alq(3) and a structural distortion of the Alq(3) molecule gives rise to a strong spin polarization in this originally nonmagnetic molecule Alq(3). The calculated total magnetic moment mainly resides on the Alq(3) molecule (0.6 mu B), while that on Cu is moderate (0.4 mu B). The finding of a spin polarization induced by the nonmagnetic element Cu is helpful for understanding of spin-related phenomenon in Alq(3) and potentially enabling future magnetic-metal-free organic spintronics.
