我们研究了空间周期静磁场中原子运动引起的原子自旋共振。以约400m S−1的速度入射到透射式磁栅上，产生一个空间周期磁场。磁栅是由在聚酰亚胺衬底上形成的磁性薄膜形成的，该聚酰亚胺衬底具有间隔150μm的多个狭缝。原子通过栅时经历了场振荡，这取决于它们的速度和场周期，并经历了磁共振。垂直磁化膜的共振光谱与面内磁化膜的共振光谱形成了鲜明的对比。前者在频率的奇数倍处有共振峰，这是由整个周期的速度决定的，而后者在相同的频率上有下降。
We studied atomic spin resonance induced by atomic motion in a spatially periodic magnetostatic field. A rubidium atomic beam, with a velocity of about 400 m s−1, was obliquely incident to a transmission magnetic grating that produced a spatially periodic magnetic field. The magnetic grating was formed by a magnetic thin film on a polyimide substrate that had multiple slits at 150 μm intervals. The atoms experienced field oscillation, depending on their velocity and the field period when passing through the grating, and underwent magnetic resonance. Resonance spectra obtained with a perpendicular magnetization film were in clear contrast to ones obtained with an in-plane magnetization film. The former exhibited resonance peaks at odd multiples of the frequency, determined by the velocity over the period, while the latter had dips at the same frequencies.
