TY - JOUR ID - citeulike:5433710 L3 - citeulike-article-id:5433710 N2 - A magnetic metal-encapsulating silicon fullerene, Eu@Si20, has been predicted by density functional theory to be by far the most stable fullerene-like silicon structure. The Eu@Si20 structure is a regular dodecahedron with Ih symmetry in which the europium atom occupies the center site. The calculated results show that the europium atom has a large magnetic moment of nearly 7.0 Bohr magnetons. The magnetic silicon fullerene may be ideal for molecular electronic devices. In addition, it was found that two kinds of stable "pearl necklace" nanowires, constructed by concatenating a series of Ih-Eu@Si20 units, each with a central europium atom retains the high spin moment. The magnetic structure of these nanowires indicates potential applications in the fields of spintronics and high-density magnetic storage.
