摘要
In order to increase the resistivity of electrodeposited high-B-s CoNiFe thin film, an organic additive such as diethylenetriamine (DET) was added to the plating bath. The desirable soft magnetic CoNiFe film with higher rho value of 95 mu Omega-cm was developed by the carbon inclusion from the new bath containing DET. The CoNiFe thin film with high rho value exhibited the excellent frequency-dependence of the permeability. Although high-rho CoNiFe thin film did not show the sufficient corrosion resistance, annealing at 250 degrees C for one hour in vacuum led to higher anticorrosion property.
