Title

Study on in-plane magnetic structure of neutron polarizing multilayer mirrors

Abstract

Neutron polarizing supermirror is increasingly important device for polarized neutron scattering experiments and needs to have high polarization performance at low externnal magnetic field. It is important to understand in-plane magnetic structure in the process of magnetization for further improvement in soft magnetic properties. Off-specular scattering (OSS) and grazing incidence small-angle neutron scattering (GISANS) measurements with polarization analysis are unique and powerful tool to study the in-plane magnetic structure in layered systems stated above. The lateral correlation length obtained by OSS and GISANS measurements is useful to get insight into the mechanism that controls the process of magnetization for polarizing supermirrors, combined with the data of x-ray diffraction and hysteresis measurements.
