Preparation and Magnetic Properties of Fe-Co–Ni Magnetic Nanowire Arrays with Three-Dimensional Periodic Structures

Ultrathin Ternary FeCoNi Alloy Nanoarrays in BaTiO3 Matrix for Room-Temperature Multiferroic and Hyperbolic Metamaterial

“…The coercivity (H C ) of all the samples is compared in Figure 3f; the 1 Hz film exhibits the highest H C-OP and H C-IP of ∼800 Oe and ∼110 Oe, respectively. Interestingly, all the other samples display soft magnetic behavior with low H C-OP and H C-IP values (less than 20 Oe), which is lower than the FCN MNAs fabricated by templated electrodeposition, 27,28 indicating their great potential in soft magnet applications. The higher H c value observed in the 1 Hz sample is attributed to the larger size of the alloy nanopillars within this film compared to those in other samples.…”

“…32 In this case, the H K values of all the films are negative, suggesting the interpillar magnetostatic dipole interaction is the dominate factor, with the easy magnetization axis perpendicular to the nanopillars' long axis (or parallel to the film surface). 27,33 It is noted that the thickness of the films was kept the same, ∼20 nm. Tuning the thickness of the films could change their magnetic anisotropy.…”
