Abstract

Magnetic films for magnetic field concentrators should have high magnetic permeability. Reproducible electrochemical deposition of Co–Ni–Fe films with predominant face-centered cubic lattice and high gain of  the weak magnetic field (related to their high magnetic permeability) was developed using a chloride electrolyte. The magnetic properties and structure of electrochemically deposited Co–Ni–Fe films with varying ratios of Co, Ni, and Fe atomic concentrations have been studied. Using the TREMAG alloy (Co60Ni20Fe20) as an example, it was established that its high permeability in weak magnetic fields is mainly determined by the crystal structure and the chosen stoichiometric composition of the Co–Ni–Fe film.
