  In the recent work arXiv:1809.02446, the authors proposed a new method
measuring the electron oscillating electric dipole moment (eOEDM) using atomic
magnetomaters. This eOEDM is induced by the interaction between the electron
magnetic dipole moment, electric field and axion field. The result is sensitive
to the axion-photon coupling according to [Hill, PRD 91, 111702 (2015)]. Here
we want to describe that the same experimental method can be also sensitive to
the axion-electron coupling according to [Alexander and Sims, PRD 98, 015011
(2018)]. In this article, we will show the corresponding sensitivity plot and
compare with other constraints.
