Both the 20- and 50-nm nanobrushes show a similar tendency of MI curves: (100) and (002) textures can both enhance the MI ratio of the nanobrush, and the (100) texture shows the best results. MI property and magnetic field sensitivity strongly depend on the film’s surface morphology and the combination of the nanowires and film. It may be the main reason that the sensitivity of the 50-nm nanobrush is not as good as that of other samples. H 89 clinical trial Figure 7 MI ratio of the nanobrush with 50-nm textured nanowires. Conclusions The MI effect of the nanobrush with FeNi film and
texture-controllable cobalt nanowires has been investigated. Cobalt nanowires with (100), (002), and mixed structures have been fabricated by different pH values and deposition temperatures. The optimized results of the (100)-textured nanobrush are 320% and 350% with
20- and 50-nm diameters, respectively. The phenomenon can be explained by the different distributions of transverse magnetic moments, induced by the selleck chemical exchange coupling effect between the interface of nanowires and film. Micromagnetic simulation shows the magnetic moment distribution when the nanowires act on the film. The parallel and perpendicular exchange coupling models are supposed to be the main reason of the different NU7441 MI performances.
