Electronic excitations of potassium intercalated manganese phthalocyanine investigated by electron energy-loss spectroscopy

Abstract

The electronic excitations of manganese phthalocyanine (MnPc) films were studied as a function of potassium doping using electron energy-loss spectroscopy in transmission. Our data reveal doping induced changes in the excitation spectrum, and they provide evidence for the existence of three doped phases: K${}_1$MnPc, K${}_2$MnPc, and K${}_4$MnPc. Furthermore, the addition of electrons first leads to a filling of orbitals with strong Mn 3d character, a situation which also affects the magnetic moment of the molecule.
