STRUCTURE, ROUGHNESS AND MAGNETIZATION BEHAVIOR OF TRIODE SPUTTERED CO11FE89-SI MULTILAYERS

A study of monochromator-type neutron mirrors, produced under differen t sputtering conditions by a triode sputtering system is presented, an d the effect on the magnetic behaviour and the film structure is revea led. Special attention was paid to the dependence of the interface rou ghness in respect to the deposition parameters. A structural character ization of the specimen was performed by X-ray reflectometry and diffr action, supported by transmission electron microscopy and electron dif fraction studies, made on ultramicrotom cuts oriented perpendicular to the surface. SQUID magnetometry and polarized neutron reflectometry i n combination with a simulation of the reflection data on the Co11Fe89 -Si system was used to examine the magnetization profile and its evane scence near the chemical interface. Mossbauer spectroscopy clarified t he model of interpretation.
