Neutrons are sensitive to magnetic fields because they have spin and no charge. The measurement of oscillating magnetic fields using neutron beams is generally done by stroboscopic methods, but it is difficult to measure high-frequency one because it changes while neutrons are passing through. Therefore, we have studied measurement of oscillating magnetic field by neutron interferometry, and have conducted experiments and formularization. We report present status.
