Abstract

We report on coherent manipulation of electron spins in an antiferromagnetically coupled spin triangle (Cu ₃-X) (X=As, Sb) impregnated in freestanding nanoporous silicon (NS) by using 240 GHz microwave pulses. Rabi oscillations are observed and the spin coherence time is found to be T ₂=1066ns at 1.5 K. This demonstrates that the (Cu ₃-X):NS hybrid material provides a promising scheme for implementing spin-based quantum gates. By measuring the spin relaxation times of samples with different symmetries and environments we give evidence that a spin chirality is the main decoherence source of spin triangle molecules.
