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 ...
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
