The structural, magnetic, and magneto-transport properties of ferromagnetic FeCoNiCuPd high-entropy alloy (HEA) thin films were investigated to assess the role of the heavy element Pd in magneto-transport. The FeCoNiCuPd films with varying composition ratios of Cu and Pd were fabricated by a co-sputtering process at ambient temperature, and the resulting films exhibited a face-centered cubic structure with a homogenous single phase. All the films exhibited ferromagnetic hysteresis curves with soft magnetic behavior at room temperature. The dependence of the anisotropic magnetoresistance effect and anomalous Hall effect on Pd suggests that heavy metals with large spin-orbit interactions play an important role in the magneto-transport of magnetic HEAs. This finding will facilitate the understanding of the magneto-transport phenomenon in magnetic HEAs for future spintronic materials.

Perpendicular magnetic anisotropy of thin films

Takanashi, Koki; Seki, Takeshi*

Magune, 19(3), p.100 - 106, 2024/06

Perpendicular magnetic anisotropy of thin films currently plays an important role in spintronics as well as magnetic recording. Regarding perpendicular magnetic anisotropy, in this article, the fundamentals, the research history, and the recent research trends are reviewed, showing specific examples with perpendicular magnetization such as magnetic multilayers, ordered alloy films, rare earth-transition metal amorphous alloy films, and inhomogeneous or granular films. The physical origins for perpendicular magnetic anisotropy, including interface anisotropy due to structural symmetry breaking, magnetoelastic anisotropy due to strain, bulk-type magnetocrystalline anisotropy, and directional pair ordering of atoms, are discussed in each example.
