abstract = {By means of ab initio calculations we predict that it is
possible to manipulate the magnetization direction in
organic magnetic molecules by changing their oxidation
state. We demonstrate this novel effect on the Eu-2(C8H8)(3)
molecule, in which the hybridization of the outer pi ring
states with the Eu 4f states causes a redistribution of the
orbitals around the Fermi level leading to a strong
ferromagnetism due to a hole-mediated exchange mechanism. As
a key result, we predict an oscillatory behavior of the easy
axis of the magnetization as a function of the oxidation
state of the molecule-a new effect, which could lead to new
technological applications.},
