Resonance transitions of atoms using a microperiodic structure : Beyond optical manipulation methods

点击翻译按钮获取中文摘要

We studied the resonance transitions of atoms interacting with a periodic magnetostatic field. We demonstrated the coherent spin manipulation by the interaction of an atomic beam (velocity : ～500m/s) with a magnetic lattice produced by an array of current-carrying wires (spacing : ～1mm). We also studied the interaction of an atomic beam (velocity : ～1m/s) with the periodically magnetized surface (period : ～4μm) of a transparent magnetic film under the influence of the evanescent wave atomic mirror. We completed the development of the experimental system, but we have not succeeded in measuring the resonance yet.
