TARGETS WITH MAGNETIC-PROPERTIES

Various multilayer targets with ferromagnetic matter as a middle layer for TF (transient magnetic field) measurements were prepared using ro lling and vacuum evaporation-condensation techniques. The compatibilit y of different backing materials with the condensed ferromagnetic matt er was investigated. The influence of the substrate temperature on the magnetic properties was analyzed as well. Ferromagnetic Fe layers con sisting of separated segments of domain size were prepared by vacuum e vaporation-condensation through suitable mesh masks. For NMR-ON (nucle ar magnetic resonance on oriented nuclei) experiments and for studies of the circular magnetic X-ray dichroism rolled foils of highly dilute d ferromagnetic alloys were needed. The preparation of such impurity s ystems by means of an electron beam source in high vacuum is described . The diluting process strongly depends on the relative vapor pressure s of the two metals.
