摘要：
Expressions for the neutron density and reflection amplitude have been obtained in the case of a magnetic neutron-wave resonator placed in a static magnetic field or in static and rotating magnetic fields. It is shown that the enhancement of the spin-flip neutron reflection coefficient and that of spin-flip neutron density are proportional to the squared and cubic enhancements of nuclear neutron absorption or the non-spin-flip neutron density, respectively. The conditions for neutron measurements with a high sensitivity of the parameters of magnetic structures have been determined.
