Experimental results of searches for axion-like dark matter using the spin-amplifier-based magnetometer.

Caption

The spin amplification technique has been demonstrated to search for ALP signals in the frequency range from 2 to 180 Hz, corresponding to the ALP mass range from 8.3 to 744 feV. (a) Limits on the axion-like dark matter-nucleon coupling gaNN. (b) Limits on dark photon-nucleon coupling gdEDM.
