“…Altogether, 129 wires were used to produce the magnetic lattice with 10 cycles of 2-mm periods and a ∼ 5 mm×30 mm beam entrance, which was large enough to accept the atomic beam. Note that currents at the edges of the arrays were halved by connecting pairs of edge wires in parallel to compensate for the distortion of the periodic field produced by a finite array of current-carrying wires [9,11].…”

“…This structure, reminiscent of a multiwire-chamber-type particle detector [10], allowed a variety of incident angles. This was unattainable with our previous version of the magnetic lattice, which was formed using a stack of printed circuit boards [9], and each atom was only able to travel through one of the gaps between two adjacent boards. This degree of freedom of the incident angle can be used to reduce the dephasing of spin nutation caused by different field amplitudes for different incident positions.…”

“…These experiments demonstrated that magnetic resonance was induced by atomic motion through an artificial magnetic lattice, referred to as "motion-induced resonance" (MIR). Sharp resonance lines were obtained, and their widths were primarily determined by the transit time through the lattice [9]. However, in both high-energy and low-energy experiments, coherent Rabi-type oscillation of the population has not been observed directly [5].…”

“…Recent progress achieved using high-energy beams of highly charged ions showed the potential for applications in high-resolution spectroscopy or even manipulation of the internal states of these ions in the X-ray region of keV or 10 18 Hz [3][4][5][6], in which the order was determined by the ion velocity (∼ 10 8 m/s) and the lattice constant (∼ 10 −10 m).

Spin nutation induced by atomic motion in a magnetic lattice

An atom moving in a spatially periodic field experiences a temporary periodic perturbation and undergoes a resonance transition between atomic internal states when the transition frequency is equal to the atomic velocity divided by the field period. We demonstrated that spin nutation was induced by this resonant transition in a polarized rubidium (Rb) atomic beam passing through a magnetic lattice. The lattice was produced by current flowing through an array of parallel wires crossing the beam. This array structure, reminiscent of a multiwire chamber for particle detection, allowed the Rb beam to pass through the lattice at a variety of incident angles. The dephasing of spin nutation was reduced by varying the incident angle.

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.

Abstract. We measured the magnetic resonance of rubidium atoms passing through periodic magnetic fields generated by two types of multi-layered transmission magnetic grating. One of the gratings reported here was assembled by stacking four layers of magnetic films so that the direction of magnetization alternated at each level. The other grating was assembled so that the magnetization at each level was aligned. For both types of grating, the experimental results were in good agreement with our calculations. We studied the feasibility of extending the frequency band of the grating and narrowing its resonance linewidth by performing calculations. For magnetic resonance precision spectroscopy, we conclude that the multi-layered transmission magnetic grating can generate periodic fields with narrower linewidths at higher frequencies when a larger number of layers is assembled at a shorter period length. Moreover, the frequency band of this type of grating can potentially achieve frequencies of up to hundreds of PHz.
