Аннотация:New experimental possibilities of investigating layeredmagnetic structures in oscillatingmagnetic fields
are discussed. Spin-flip and nonspin-flip neutron reflection and transmission probabilities show a
frequency dependency near the magnetic neutron resonance condition. This allows to increase the
precision of the static magnetic depth profile measurements of the magnetized matter. Moreover, this
opens new possibilities of measuring the induction of the oscillating field inside the matter and
determining the magnetic susceptibility of the oscillating magnetic field. Refraction of neutrons as they
pass through amagnetic prism in the presence of an oscillatingmagnetic field is also investigated. A nonpolarized
neutron beam splits into eight spatially separated neutron beams, whose intensity and
polarization depend on the strength and frequency of the oscillating field. Also, it is shown that the
oscillating magnetic permeability of an angstrom-thick layer can be measured with a neutron wave
resonator.
