摘要

在这项研究中，我们利用连续中子束评估了高频磁场下的自旋干涉测量。我们推导出了中子自旋干涉与平行于量子化轴的振荡磁场的解析公式。该公式表明，干涉图案的相位没有发生偏移，但其振幅或能见度因振荡磁场而减小。在 MINE2 进行的实验有效地再现了这一现象，振幅减小的程度也符合公式。单色中子束波长较长，例如 MINE2 的波长为 8.8 Å，因此很容易将中子束偏振，从而进行高可见度的自旋干涉测量实验。因此，MINE2 可用于测试基于中子自旋光学的新现象。

A Study of Oscillating Magnetic Fields with Neutron Spin Interferometry

In this study, we evaluate spin interferometry with high-frequency magnetic fields using a continuous neutron beam. We derive an analytical formula for neutron spin interference with oscillating magnetic fields parallel to the quantization axis. The formula indicates that the phase of the interference pattern was not shifted but its amplitude, or visibility, was reduced by the oscillating magnetic fields. The experiment at MINE2 effectively reproduced this phenomenon and the degree of the amplitude reduction also followed the formula. Monochromatic neutron beams with long wavelengths such as 8.8 Å at MINE2 make it easy to polarize the beams to conduct high-visibility spin interferometric experiments. As a result, MINE2 is useful for testing new aspects of phenomena based on neutron spin optics.
