Detecting and controlling nuclear spin nano-ensembles is crucial for the further development of nuclear magnetic resonance (NMR) spectroscopy and an important step towards a nuclear spin based quantum simulator. Here we demonstrate a method for coherent control of few tens of nuclear spins by using radio frequency pulses. A single nitrogen-vacancy center in diamond (NV) is used for polarization of the nuclear spins and the readout of their magnetization. The experiments are performed on a nanometer thick layer of 13C enriched single crystal diamond doped with NV centers embedded in a nuclear spin free 12C diamond matrix. We demonstrate the basic coherent control experiments - Rabi oscillations, Ramsey spectroscopy and Hahn echo, though any NMR pulse sequence can be implemented.
