Abstract
An axion dark matter search with the CAPP-8TB haloscope is reported. Our results are sensitive to axion-photon coupling ${g}_{a\ensuremath{\gamma}\ensuremath{\gamma}}$ down to the QCD axion band over the axion mass range between 6.62 and $6.82\text{ }\text{ }\ensuremath{\mu}\mathrm{eV}$ at a 90% confidence level, which is the most sensitive result in the mass range to date.
