Abstract

This letter presents a power consumption reduction scheme of magnetic microactuation using Cu-Ni nanocomposite film which is electroplated in alkaline noncyanide based Ni colloidal copper plating solution at 40 °C. The superconducting quantum interference device magnetometer measurements show that Cu film is modified from diamagnetism to ferromagnetism via the incorporation of Ni ferromagnetic nanoparticles into itself to form a Cu-Ni nanocomposite film. A magnetic microactuator made of the nanocomposite can have about 9% performance improvement in terms of actuation enlargement. In other words, the coil made of the Cu-Ni nanocomposite can exhibit better power efficiency for the same output displacement.
