  text: We propose a method for detecting many-body localization (MBL) in disordered
    spin systems. The method involves pulsed coherent spin manipulations that probe
    the dephasing of a given spin due to its entanglement with a set of distant spins.
    It allows one to distinguish the MBL phase from a noninteracting localized phase
    and a delocalized phase. In particular, we show that for a properly chosen pulse
    sequence the MBL phase exhibits a characteristic power-law decay reflecting its
    slow growth of entanglement. We find that this power-law decay is robust with
    respect to thermal and disorder averaging, provide numerical simulations supporting
    our results, and discuss possible experimental realizations in solid-state and
    cold-atom systems.
