NW axis.In the simulated hysteresis loops on the isolated Fe/Cu NWs together with the magnetic From the simulated hysteresis loops of the isolated Fe/Cu NWs with all the magnetic field applied along the wire axis, we’ve extracted the coercivity fields (HCC)as a function field applied along the wire axis, we’ve got extracted the coercivity fields (H) as a function from the variety of bilayers (open symbols in Figure 4c) and for the lengthy Fe NWs (continuous with the quantity of bilayers (open symbols in Figure 4c) and for the lengthy Fe NWs (continuous blue line in Figure 4c). In spite of the important distinction among the HCCvalues obtained blue line in Figure 4c). Despite the substantial difference in between the H values obtained experimentally and the simulated ones, a a very good correlation with the experimental CC 122 site information the simulated ones, great correlation together with the experimental data was experimentally was achieved (Figure 4b,c). Low-aspect-ratio segmented NWs with 35-nm-length Fe achieved (Figure 4b,c). Low-aspect-ratio segmented NWs with 35-nm-length Fe Repotrectinib custom synthesis segments segments present a behavior like a set of set of non-interacting nanoparticles when they present a behavior just about nearly like a non-interacting nanoparticles after they are are separated by 120-nm-length non-magnetic Cu spacers[19]. Even so, when we boost separated by 120-nm-length non-magnetic Cu spacers [19]. Nevertheless, when we enhance the Fe length to 300 nm, the contribution in the magnetostatic interactions isn’t negligible, the Fe length to 300 nm, the contribution on the magnetostatic interactions is just not negligible, as shown in Figures 33 and 4. The coercive field progressively increases using the number as shown in Figures and four. The coercive field progressively increases using the variety of bilayers due due to the magnetostatic coupling in between involving Fe segments, but the of bilayers to the small modest magnetostatic coupling Fe segments, but the maximum value obtained does not attain the HC on the continuous Fe NW, because the interaction in between layers is restricted by the Cu separation.Nanomaterials 2021, 11, x FOR PEER REVIEW7 ofNanomaterials 2021, 11,maximum worth obtained will not reach the HC from the continuous Fe NW, since the interaction involving layers is restricted by the Cu separation. 3.3.2. Varying the Fe Length three.3.2. Varying7 ofAfter analyzing Immediately after analyzing the magnetic behavior of Fe/Cu NWs as a function of the number of Fe/Cu NWs as a function of bilayers, within this section we focus our focus on understanding the influence on the bilayers, within this section we concentrate our interest on understanding the influence from the length in the of the Fe layer on the interactions in between the magnetic layers. For that we’ve length Fe layer around the interactions amongst the magnetic layers. For that objective,goal, prepared multiple Fe/Cu Fe/Cu NWs’ samples, the amount of bilayers was fixed fixed we’ve ready multipleNWs’ samples, exactly where where the amount of bilayers was to 15, plus the Fe segments’ length was varied varied between 20 nm.
