Targets with magnetic properties

Abstract Various multilayer targets with ferromagnetic matter as a middle layer for TF (transient magnetic field) measurements were prepared using rolling and vacuum evaporation-condensation techniques. The compatibility of different backing materials with the condensed ferromagnetic matter was investigated. The influence of the substrate temperature on the magnetic properties was analyzed as well. Ferromagnetic Fe layers consisting of separated segments of domain size were prepared by vacuum evaporation-condensation through suitable mesh masks. For NMR-ON (nuclear magnetic resonance on oriented nuclei) experiments and for studies of the circular magnetic X-ray dichroism rolled foils of highly diluted ferromagnetic alloys were needed. The preparation of such impurity systems by means of an electron beam source in high vacuum is described. The diluting process strongly depends on the relative vapor pressures of the two metals.
