【 摘 要 】
We present an experimental and theoretical study of a magnetic single-molecule transistor based on N@C-60 connected to gold electrodes. Particular attention is paid to the regime of intermediate molecule-lead coupling, where cotunneling effects manifest themselves in the Coulomb-blockade regime. The experimental results for the differential conductance as a function of bias, gate voltage, and external magnetic field are in agreement with our analysis of the tunneling rates and provide evidence of magnetic signatures in single-N@C-60 devices arising from an antiferromagnetic exchange interaction between the C-60 spin and the nitrogen spin.
