Spin-Dependent Hybridization between Molecule and Metal at Room Temperature through Interlayer Exchange Coupling
2015
We experimentally and theoretically show that the magnetic coupling at room temperature between paramagnetic Mn within manganese phthalocyanine molecules and a Co layer persists when separated by a Cu spacer. The molecule’s magnetization amplitude and direction can be tuned by varying the Cu–spacer thickness and evolves according to an interlayer exchange coupling mechanism. Ab initio calculations predict a highly spin-polarized density of states at the Fermi level of this metal-molecule interface, thereby strengthening prospective spintronics applications.
