Sažetak
In this article, we briefly summarize our results gained from recent density functional theory simulations aimed to investigate the interaction between organic materials containing pi-electrons (i.e., several benzene-like molecules and graphene) with ferromagnetic surfaces. We show how the strong hybridization between the p(z)-electrons that initially form the pi molecular orbitals with the magnetic d-states of the metal influences the spin polarization, the magnetic exchange coupling, and the magnetization direction at hybrid organic ferromagnetic interface. From a practical perspective, these properties play a very important role for device applications based on organic materials and magnetic surfaces.
