Strain-induced perpendicular magnetic anisotropy of 〈100〉-oriented Ni-Cu superlattices

Selective-Resputtering-Induced Perpendicular Magnetic Anisotropy in Amorphous TbFe Films

“…In crystalline films, where magnetic anisotropy arises predominantly from magnetocrystalline interactions [1], some form of crystal texturing is often responsible. Alternative sources of magnetic anisotropy include columnar growth [2], anisotropic void networks [3], chemical short range order [4,5], and anisotropic stress fields [6,7]. These provide magnetic anisotropy from dipole-dipole (or pseudodipolar) interactions [8] and magnetoelastic interactions [1] (i.e., magnetostriction), respectively.…”

Evidence for a strain-induced variation of the magnetic moment in epitaxial Cu/Ni/Cu/Si(100) structures

“…However, strain is also a very important property of epitaxial thin films, giving rise to a magnetic anisotropy through the magnetoelastic interaction. In epitaxial Ni/Cu͑001͒ PMA occurs for a surprisingly large thickness range [6][7][8] and is explained by magnetoelastic anisotropy caused by the in-plane lattice mismatch between Ni and Cu. However, the strain dependence of the magnetic moment has not been well studied experimentally in epitaxial transitionmetal films.…”

Perpendicular magnetic anisotropy in sputtered amorphous TbFeCo films

“…It is well known that in crystalline films the magnetic anisotropy is originated from magnetocrystalline anisotropy [3]. There are other mechanism of magnetic anisotropy such as stress-induced magnetic anisotropy [4], shape anisotropy [5]. However, none of the above mechanisms can explain the PMA in amorphous TbFeCo films just because of the uniformity of the amorphous nature.…”
