Electronic spins in solid-state media have recently attracted large interest in quantum information science. Their large magnetic moments offers fast operations in computation and communication applications and high sensitivity for sensors. However, this implies also high sensitivity to magnetic noise, thus reducing coherence times. In our work, we demonstrate strong suppression of decoherence in an isotopically purified 171Yb:YSO crystal by inducing clock transitions simultaneously in the microwave and optical domains. Our technique allows to reach coherence times above 0.1ms and 1ms for optical and microwave transitions respectively, and can in principle be generalized to other media with strongly anisotropic hyperfine interaction. Our results show the great potential of 171Yb:YSO for optical quantum memories, microwave-optical transducers and single spin detection.
