Electrodeposition of thin soft-magnetic layers in magnetic gradient fields — •Kristina Tschulik, Jakub Koza, Margitta Uhlemann, Annett Gebert, and Ludwig Schultz — Leibniz Institute for Solid State and Materials Research Dresden, P.O. Box 270016, D-01171 Dresden, Germany

Thin soft magnetic layers are of interest as sensor layers or as write head component in magnetic data storage devices. Due to the fact, that in these fields of applications high saturation magnetization in combination with low coercivity is desired, deposits based on iron and cobalt are favorable. As it has already been shown, externally applied homogeneous magnetic fields can significantly influence the deposition process as well as morphology, texture and magnetic properties of deposits. Hence, influencing these deposit properties should be possible by tailoring the magnetic field distribution applied during the deposition process, which in turn can be generated via different arrangements of magnets. Therefore electrochemical measurements in various magnetic gradient fields have been performed and the resulting deposits have been characterized via optical microscopy, SEM, AFM, MFM, XRD and MOKE.
