Abstract

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 H_c ≈ 700 Oe at 300 K as compared to those of Co nanoclusters (K₁ ≈ 2.9 Mergs/cm ³ and H_c ≈180 Oe).
