Study of the in-plane magnetic structure of neutron polarizing multilayer mirrors
Neutron polarizing supermirrors are increasingly important devices for polarized neutron scattering experiments and need to have high polarization performance at low external magnetic fields. It is important to understand the in-plane magnetic structure in the magnetization process for further improvement in the soft magnetic properties. Off-specular scattering (OSS) and grazing incidence small-angle scattering (GISAS) measurements with polarized neutrons are unique and powerful tools to study the in-plane magnetic structure in layered systems. The lateral correlation length obtained by OSS and GISAS measurements, combined with X-ray diffraction and hysteresis measurements, is useful to get insight into the mechanism that controls the magnetic properties of multilayers for polarizing supermirrors.
