Description

Polarizing multilayers and supermirrors for applications in neutron instrumentation have been produced using DC-magnetron sputtering. The chosen material combination Ti1-uNu-Fe0.50Co0.48V0.02 offers the possibility to adjust the scattering length density of the 'contrast' material Ti to the value being effective on neutrons in the /->-state in the FeCoV alloy magnetized to saturation, by loading Ti with the suited amount of nitrogen. Neutron reflectometry data for supermirrors give flipping ratios of 40 and more and reflectivities better than 85% at twice the critical angle of Ni. The production process induces a magnetic anisotropy for directions lying within the layer plane. Ti1-vGdv absorbing subcoatings have been used to suppress the remaining reflectivity of the unwanted spin component from the substrate-mirror interface. SQUID and MOKE magnetometry accompanied the experiments performed with polarized neutrons. (author) 8 figs., 18 refs
