| 中文摘要 | A series of composite structured CoxCu1-x (x = 0.38-0.87) nanowire arrays have been successfully deposited in the same Co2+/Cu2+ = 10 : 1 solution by applying various depositing potentials. We found that the struetures of CoxCu1-x composite nanowires regularly changed with increase of Cu content, thus causing regular change of the magnetic properties of CoCu nanowires. With the percent. content of Cu increasing, part of Cu and Co form metastable face-centred cubic (fcc) CoCu solid solution which decreases the competition between the crystallographic anisotropy and shape anisotropy and improves the squareness of CoCu nanowires; the remaining pari of Cu exists in the nanowires as fcc Cu crystals which destroy the crystallographic anisotropy and increases the pinning of domain walls, thus improves the squareness and coercivity of CoCu nanowires. Comparing CoxCu1-x. nanowires of different compositions, we found that the nanowires have their maximum of the squareness (M-r/M-s) and coercivity (H-c) values for Co-75 Cu-25 and Co-60 Cu-40, respectively. Because of the special composite structures, the values exceed those of single phase CoCu nanowire with the same diameter. |
