Polarized neutron reflectometry with neutron spin analysis is used to investigate the magnetic properties of a large array of ferromagnetic Co dots with in-plane magnetization. The diffuse neutron reflectivity contains resonant intensity peaks due to the lateral periodicity of the dot array. Using polarized neutrons, the intensity of the resonant peak in the diffuse neutron reflectivity is monitored as a function of an external magnetic field applied in the sample plane. Spin analysis of the reflected neutrons reveals the magnetization reversal and saturation within the dots. (C) 2001 Elsevier Science BN. All rights reserved.
