Electrical Readout of Individual Nuclear Spin Trajectories in a Single-Molecule Magnet Spin Transistor
Résumé
We present the electrical readout of time trajectories obtained from an isolated nuclear spin. The device, a TbPc2 single-molecule magnet spin transistor, detects the four different nuclear spin states of the Tb3+ ion with fidelities better than 69%, allowing us to measure individual relaxation times (T1) of several tens of seconds. A good agreement with quantum Monte Carlo simulations suggests that the relaxation times are limited by the current tunneling through the transistor, which opens up the possibility to tune T1 electrically by means of bias and gate voltages.
