Pulse Reversal PermAlloy Plating Process for MEMS Applications

Pulse and pulse reverse plating—Conceptual, advantages and applications

A review on pulse and pulse reverse techniques for electrodeposition have been attempted. Pulse electrodeposition (PED) of some metals and lloys are reported. The effects of mass, transport, electrical double layer pulse parameters and current distribution on surface roughness and orphology are presented. Applications, advantages and disadvantages of PC and PRC techniques are discussed along wi...

An Improved Plating Process

Microtubes, are a basic component for a myriad of potential products. They are very small tubes (hundreds can fit ina human hair) that can be made from practically any material. Tubes larger than 1 micron diameter can be made withany cross-sectional shape desired. The significance of microtubes and microtnbe composites is that they provide theopportunity to miniaturize (even to the ...

Controlled magnetic reversal in Permalloy films patterned into artificial quasicrystals.

We have patterned novel Permalloy thin films with quasicrystalline Penrose P2 tilings and measured their dc magnetization and ferromagnetic resonance absorption. Reproducible anomalies in the hysteretic, low-field data signal a series of abrupt transitions between ordered magnetization textures, culminating in a smooth evolution into a saturated state. Micromagnetic simulations compare well to ...
