dc.description.abstract
The time-window for processing electron spin information (spintronics) in
solid-state quantum electronic devices is determined by the spin–lattice and
spin–spin relaxation times of electrons. Minimizing the effects of spin–orbit
coupling and the local magnetic contributions of neighbouring atoms on
spin–lattice and spin–spin relaxation times at room temperature remain
substantial challenges to practical spintronics. Here we report conduction
electron spin–lattice and spin–spin relaxation times of 175 ns at 300 K in
37±7 nm carbon spheres, which is remarkably long for any conducting solid-
state material of comparable size. Following the observation of spin
polarization by electron spin resonance, we control the quantum state of the
electron spin by applying short bursts of an oscillating magnetic field and
observe coherent oscillations of the spin state. These results demonstrate the
feasibility of operating electron spins in conducting carbon nanospheres as
quantum bits at room temperature.
