| Abstract: | We demonstrated spin echoes of nuclear spins in a spin injection device with a highly polarized spin source by nuclear magnetic resonance (NMR). Efficient spin injection into GaAs from a half-metallic spin source of Co2MnSi enabled efficient dynamic nuclear polarization (DNP) and sensitive detection of NMR signals even at a low magnetic field of similar to 0.1 T and a relatively high temperature of 4.2K. The intrinsic coherence time T-2 of Ga-69 nuclear spins was evaluated from the spin-echo signals. The relation between T-2 and the decay time of the Rabi oscillation suggests that the inhomogeneous effects in our system are not obvious. This study provides an all-electrical NMR system for nuclear-spin-based qubits. |
