It therefore provides a complementary probe of the axion-electron coupling $g_{ae}$ beyond the conventional axion-photon coupling $g_{a \\gamma}$ in cavities. We show that existing axion cavity experiments can constrain the coupling to $g_{ae}\\lesssim 10^{-5}$ over the scanned axion mass ranges, $1\\,\\mu\\, {\\rm eV}\\lesssim m_a\\lesssim 20\\,\\mu\\,{\\rm eV}$.
