We constrain the coupling between axionlike particles (ALPs) and photons,measured with the superconducting resonant detection circuit of a cryogenicPenning trap. By searching the noise spectrum of our fixed-frequency resonantcircuit for peaks caused by dark matter ALPs converting into photons in thestrong magnetic field of the Penning-trap magnet, we are able to constrain thecoupling of ALPs with masses around $2.7906-2.7914\,\textrm{neV/c}^2$ to$g_{a\gamma}< 1 \times 10^{-11}\,\textrm{GeV}^{-1}$. This is more than oneorder of magnitude lower than the best laboratory haloscope and approximately 5times lower than the CERN axion solar telescope (CAST), setting limits in amass and coupling range which is not constrained by astrophysical observations.Our approach can be extended to many other Penning-trap experiments and has thepotential to provide broad limits in the low ALP mass range.
