Nuclear spins in the solid state environment of diamond are highly coherent,\nbut difficult to rapidly control due to the small nuclear gyromagnetic ratio.\nHere we demonstrate a more than 50-fold enhancement of the effective nuclear\ngyromagnetic ratio by coupling the nuclear spin to an electronic spin of a\nnitrogen-vacancy (NV) center in diamond. The enhancement allows for faster\nnuclear spin rotations and is in good agreement with second-order perturbation\ntheory. The method may be applied to other systems with similar\nelectron-nuclear spin interactions, such as phosphorous donors in silicon,\nopening up the possibility of fast and direct nuclear spin control in coupled\nspin systems.\n
