    "abstract": "Cryogenically cooled microelectromagnet mirrors were used to reflect a cloud\nof free-falling laser-cooled 85Rb atoms at normal incidence. The mirrors\nconsisted of microfabricated current-carrying Au wires in a periodic serpentine\npattern on a sapphire substrate. The fluorescence from the atomic cloud was\nimaged after it had bounced off a mirror. The transverse width of the cloud\nreached a local minimum at an optimal current corresponding to minimum mirror\nroughness. A distinct increase in roughness was found for mirror configurations\nwith even versus odd number of lines. These observations confirm theoretical\npredictions.",
