1. A three-dimensional electrodeposited structure, comprising:
a base structure; and
an electrodeposited material selected from the group consisting of: NiFeX, CoFeX, CoFeNiX, CoFeXY, and NiFeXY provided on the base structure, wherein at least a portion of the electrodeposited material and the base structure comprise at least one feature,
wherein the electrodeposited material comprises at least a deposited non-diffusion-controlled species and a deposited diffusion-controlled species,
wherein the electrodeposited material comprises a surface having an irregular topography with a size and shape comprising a varied length, width, or height dimension corresponding to the at least one feature,
wherein the deposited non-diffusion-controlled species comprises Ni, Fe, Co, or a combination thereof, and is present in a first concentration substantially uniform over, and substantially independent of, the topography of the surface,
wherein the deposited diffusion-controlled species comprises additive X, Y, or X and Y, and is selected from the group consisting of: Re, Ir, Os, Pt, W, Ta, Rh, Au, Ag, Cu, Pd, Ru, S, Sb, Sn, P, O, and a combination thereof, and is present in a second concentration that is lower than the first concentration over the surface, wherein the second concentration is varied over the surface corresponding to the varied length, width, or height dimension of the irregular topography of the surface corresponding to the at least one feature, wherein the second concentration is non-uniformly varied over the surface in a linear and/or non-linear manner corresponding to at least a size or shape of the at least one feature, and wherein the first concentration is substantially uniform over the surface such that the first concentration varies less than the second concentration over the surface.
