The possibility to generate and control x-ray frequency combs via periodic manipulation of the hyperfine magnetic field B in a nuclear forward scattering (NFS) setup is investigated theoretically. We consider NFS of x-ray pulses off a thin sample containing 57Fe Mößbauer nuclei. These nuclei present a very narrow-band resonance at 14.4 keV. The magnetic field manipulation relies on periodic sequences of switching off and back on the B-field, which corresponds to coherent storage of the x-ray photon, and phase modulation by employing rotations by 180° of the B-field direction. Our numerical results show that xray combs with very narrow, equidistant peaks around the nuclear resonance energy can be generated and manipulated by tuning the parameters of the magnetic field switching sequence. Possible applications for metrology and quantum technology are anticipated
