摘要：

The electronic properties of fee Cu(100) and Co(100) surfaces and of the Co/Cu (100) interface are studied by the surface Green function matching method and an empirical tight-binding model. The band structures and layer densities of states allow us to establish the short-range character of surface and interface-induced effects. The Co surface exhibits a slightly reduced magnetic moment. At the interface, the spin polarizations and magnetic moments for both localized d-electrons and nearly free sp electrons are induced at the Cu layer.
