Abstract

We propose a potential scheme, based on the achieved technique of a single-electron transistor, to implement the readout of an electronic spin state inside a doped C₆₀ fullerene by means of the magnetic dipole-dipole coupling and spin filters. In the presence of an external magnetic field, we show how to perform the spin state detection by transforming the information contained in the spin state into the tunneling current. The robustness of our scheme against sources of error is discussed.
