摘要：

We have deflected a beam of metastable helium atoms using the inhomogeneous magnetic field above a microfabricated electromagnet mirror. The mirror consisted of a single current-carrying wire in a periodic serpentine pattern on a planar sapphire substrate. A time-dependent current (and magnetic field) synchronized with a pulsed thermal atomic beam was used to compensate for the chromaticity of the deflection. The freedom to fabricate a wide variety of geometries and to employ time-dependent fields make microelectromagnets promising new tools for atom manipulation. [S0031-9007(98)06811-2].
