We report the first results of a high-sensitivity ({approximately}10{sup {minus}23} W) search for light halo axions through their conversion to microwave photons. At the 90{percent} confidence level, we exclude a Kim-Shifman-Vainshtein-Zakharov axion of mass 2.9{times}10{sup {minus}6} to 3.3{times}10{sup {minus}6} eV as the dark matter in the halo of our galaxy. {copyright} {ital 1998} {ital The American Physical Society}
