Abstract :
Electron beam lithography combined with electrodeposition was used to fabricate arrays of NiFe and Fe nanomagnets with high aspect ratios (height/diameter). MFM-measurements show the single domain behavior of the NiFe-pillars, which have an easy axis parallel to their long axis. AGM-measurements carried out on large NiFe-arrays clearly show the increasing importance of interaction effects with decreasing periodicity. On top of overgrown Fe-pillars a nanocrystalline structure can be observed
