abstract = {By means of ab initio calculations and spin-polarized
scanning tunneling microscopy experiments the creation of a
complex energy dependent magnetic structure with a tailored
spin-polarized interface is demonstrated. We show this novel
effect by adsorbing organic molecules containing pi(p(z))
electrons onto a magnetic surface. The hybridization of the
out-of-plane p(z) atomic-type orbitals with the d states of
the metal leads to the inversion of the spin polarization at
the organic site due to a p(z)-d Zener exchange-type
mechanism. As a key result, we demonstrate the possibility
to selectively and efficiently inject spin-up and spin-down
electrons from a ferromagnetic-organic interface, an effect
which can be exploited in future spintronic devices.},
