The electrodeposition and the annealing of CoFeCr alloy were explored. This material was elaborated by pulse plating technique. The evolution of resistivity as a function of the amount of chromium was studied. After a specific annealing treatment, Co_(86)Fe_(12)Cr_2 films exhibit very good soft magnetic properties and high saturation magnetization: H_c < 0.5 Oe, H_k = 20 Oe, μ_(eff) = 700 up to 150 MHz (for 1 μm) and B_s = 1.8 T. Magnetic domains and crystal structure of this alloy were characterized. CoFeCr films were integrated into magnetic devices using conventional micro-technology processes.
