Abstract
During the last few years different techniques have become available to study transport through an individual magnetic molecule. In a spin transistor, the magnetic molecule links two electrodes that are used to apply a bias voltage; a third gate electrode controls the position of molecular levels such that resonant tunneling and different redox states become accessible. Sequential single-electron transport and current suppression (Coulomb blockade) are generally observed. In this chapter, we show that spectroscopic information obtained from these three-terminal measurements confirms the high-spin state and magnetic anisotropy of the robust Fe4 single-molecule magnet incorporated in the junction. Moreover, we find that the electric gate field drastically modifies the magnetic properties of the oxidized or reduced molecule.

Note that α, the angle of rotation, is in general different from θ, the angle between the easy axis and the magnetic field.
