Zusammenfassung, Abstract
The influence of He+ (10 keV) ion bombardment on magnetic properties of sputter deposited Ni80Fe20/Au/Co/Au layered films was studied. The variable parameters were the thickness of the Co layer or Au spacer and the ion dose. The magnetooptical Kerr measurements were performed on samples with wedge shaped Co or Au layers. With increasing dose of helium ions the following changes in magnetic properties were observed: (i) a decrease in the Co thickness range corresponding to the perpendicular anisotropy, (ii) a decrease in the coercive field (HC), (iii) an increase in the ferromagnetic coupling between ferromagnetic layers.
