We report the first results of a high-sensitivity (10^-23W) search for light halo axions through their conversion to microwave photons. At the 90% confidence level, we exclude a Kim-Shifman-Vainshtein-Zakharov axion of mass 2. 910^-6 to 3. 310^-6eV as the dark matter in the halo of our galaxy.
Hagmann et al. (Mon,) studied this question.
