Paper Abstract

Polarized neutron experiments of both reflection and small angle scattering by using mainly pulsed neutrons were performed from various magnetic superlattice films. The long range order in a magnetic unit cell is determined by the conventional neutron diffraction method. Besides the order of the atomic magnetic moment, the semi-macroscopic, often called mesoscopic modulation of magnetization averaged over the magnetic layer is determined by the surface reflection as well as the small angle diffraction. The effect of giant magneto- resistance of a current topic in the solid state physics is strongly related to the semimacroscopic magnetic structure or interface magnetization. The present paper shows that the polarized neutron reflection as well as the small angle diffraction by using long wavelength polarized neutrons are indispensable tools for the magnetic structure investigation related to this subject.
