Co(Zr) nanoclusters having a small fraction of Zr (≤ 7.8 at. %) were produced using a cluster deposition method and aligned using a magnetic field of about 5 kOe prior to deposition. This study shows that Zr addition to Co nanoclusters improves the fraction of hexagonal close-packed structure, magnetic anisotropy, and easy-axis alignment process. Co(Zr) nanoclusters having 7.8 at. % of Zr exhibit a considerably enhanced magnetic anisotropy constant K1 ≈ 6.7 Mergs/cm3 and coercivity Hc ≈700 Oe at 300 K as compared to those of Co nanoclusters (K1≈ 2.9 Mergs/cm3 and Hc ≈180 Oe).
