FCC/BCC competition and enhancement of saturation magnetization in nanocrystalline Co-Ni-Fe films

Structure, chemical composition and magnetic properties of electrochemically deposited nanocrystalline Co-Ni-Fe films were investigated by a number of techniques. A high saturation magnetic induction up to $B_s=21\,$kG was attained. An enhancement of saturation magnetization, compared to an ideal anticipated one was revealed, which correlated with the nonlinear behavior of structural phase composition and lattice parameters with the change of the composition.
