Abstract

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.

Fe-W supermirrors for polarizing neutrons

Conference Majkrzak, C F ; Neumann, D A ; Copley, J R.D. ; ...

Polarized neutrons play an important role in scattering studies of condensed matter. Consequently, an efficient means of polarizing a neutron beam is very valuable. In addition to conventional, bulk single-crystal polarizers such as the Heusler alloy Cu{sub 2}MnAl, polarizing mirrors are often used for this purpose. Thin film bilayers of ferromagnetic Fe and nonmagnetic W have been deposited by sputtering on flat glass substreates according to a sequence of gradually varying bilayer thicknesses which in effect extends the critical angle for external mirror reflection for neutrons of one spin state when the Fe is magnetized in the plane of themore »« less

Structure and magnetism of Fe/Si multilayers grown by ion-beam sputtering

Journal Article Chaiken, A ; Michel, R P ; Wall, M A - Physical Review, B: Condensed Matter

Ion-beam sputtering has been used to prepare Fe/Si multilayers on a variety of substrates and over a wide range of temperatures. Small-angle x-ray-diffraction and transmission electron microscopy experiments show that the layers are heavily intermixed although a composition gradient is maintained. When the spacer layer is an amorphous iron silicide, the magnetic properties of the multilayers are similar to those of bulk Fe. When the spacer layer is a crystalline silicide with the {ital B}2 or DO{sub 3} structure, the multilayers show antiferromagnetic interlayer coupling like that observed in ferromagnet/paramagnet multilayers such as Fe/Cr and Co/Cu. Depending on the substratemore »« less

Structure and magnetic properties of magnetron-sputtered Fe/Cu multilayered thin films

Journal Article Cheng, S F ; Mansour, A N ; Teter, J P ; ... - Physical Review, B: Condensed Matter; (United States)

The structure and magnetic properties of Fe/Cu multilayered films with a constant total Fe thickness of 1050 A but varying Fe-layer thickness from 6.3 to 42 A and varying Cu to Fe thickness ratio from 1 to 3 were investigated using x-ray diffraction (XRD), x-ray absorption fine-structure (XAFS) spectroscopy, and magnetic measurements. Samples were prepared at room temperature on mica, glass, and silicon substrates using the dc-magnetron-sputtering method. For films with the same Fe-layer thickness, it was found that the magnetic moment of Fe decreases with increasing thickness ratio of Cu to Fe. For films with a Cu to Femore »« less

Fabrication of high-reflectance Mo--Si multilayer mirrors by planar-magnetron sputtering

Journal Article Stearns, D G ; Rosen, R S ; Vernon, S P - Journal of Vacuum Science and Technology, A (Vacuum, Surfaces and Films); (United States)

Molybdenum--silicon multilayer (ML) x-ray mirrors have been fabricated using a direct-current planar magnetron sputtering system. The ML structure has been characterized using x-ray diffraction and high-resolution electron microscopy, and the normal incidence x-ray reflectivity has been measured using synchrotron radiation. A striking dependence of the ML morphology on the sputtering gas pressure is observed, exhibiting a transition from layer growth at lower pressures to columnar growth at higher pressures. Correspondingly, the normal incidence x-ray reflectivity is found to decrease strongly with increasing gas pressure. By depositing Mo--Si ML at low sputtering gas pressures we have achieved a normal incidence reflectivitymore » as high as 61% at 132 A.« less

Growth, structure, and performance of depth-graded W/Si multilayers for hard x-ray optics

Journal Article Windt, D L ; Christensen, F E ; Craig, W W ; ... - Journal of Applied Physics

We describe the development of depth-graded W/Si multilayer films prepared by magnetron sputtering for use as broad-band reflective coatings for hard x-ray optics. We have used specular and nonspecular x-ray reflectance analysis to characterize the interface imperfections in both periodic and depth-graded W/Si multilayer structures, and high-resolution transmission electron microscopy (TEM) and selected area electron diffraction (SAED) to characterize the interface structure and layer morphology as a function of depth in an optimized depth-graded multilayer. >From x-ray analysis we find interface widths in the range {sigma}=0.275-0.35 nm for films deposited at low argon pressure (with a slight increase in interfacemore »« less
