Electrodeposition of NiFe and Fe nanopillars

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.

Switching behavior of single nanowires inside dense nickel nanowire arrays

“…Patterned perpendicular storage media consisting of magnetic nanowire arrays [1]- [4] in an magnetically insulating matrix allow high storage densities [5]. More than 700 Gbit/in areal density has been predicted for these structures.…”

CdTe semiconductor nanowires and NiFe ferro-magnetic metal nanowires electrodeposited into cylindrical nano-pores on the surface of anodized aluminum

“…Using commercially available ion-track etched polycarbonate membrane filters or anodized aluminum oxide membrane filters, Bi 2 Te 3 [4], CdTe [5] and PbSe [6] semiconductor nanowires or Co/Cu [7][8][9], NiFe/Cu [10] and CoNiCu/ Cu [11] multilayered magnetic nanowires have been synthesized and characterized. Recently, Zenger et al reported the electrodeposition of NiFe and Fe nanopillars using a PMMA template synthesis technique [12]. In this report, the single domain character of a NiFe nanopillar has been demonstrated.…”

Effects of ultrasonic field in pulse electrodeposition of NiFe film on Cu substrate

“…NiFe films have been deposited using various standard deposition techniques such as electrodeposition [2][3][4][5], sputtering [6,7], ultra-high vacuum evaporator [8], pulse laser deposition system (PLD) [9], metal oxide chemical vapor deposition (MOCVD) [10] and spin-coating [11]. PLD system is expensive and needs high heating rate of target surface.…”
