Thin-film multilayer reflections for polarizing neutrons have been fabricated by sputtering bilayers of ferromagnetic iron (Fe) and non-magnetic silicon (Si) onto flat glass substrates. The multilayers were deposited according to the independent variation of one of four parameters: number of bilayers; bilayer thickness (D-spacing); argon sputtering gas pressure; and target power. The relationship between the measured neutron reflectivities of these multilayers and the expected theoretical values is discussed with respect to the deposition parameters. 6 refs., 2 figs., 4 tabs.
