“…For this reason, shape anisotropy has been often employed as a tool to sustain a certain resistance to demagnetization in high-magnetization systems, for instance, by fabricating high-aspect-ratio transition-metal structures. , A great deal of work has been focused on Co nanowires (NWs) owing to the relatively large magnetocrystalline anisotropy of Co compared to other magnetic transition metals such as Fe and Ni. − Promising results ,, have been obtained in this system, including the fabrication of NW-only dense pellets with improved magnetic properties. , Fe, FeNi, and FeCo nanowires have been investigated as well. − They present larger magnetization and lower coercivity than Co, which makes them suitable for a wide array of application sectors that include biomedical, − environmental (in this case, ferrite NWs), and sensors, among others. In addition, arrays of low-coercivity NWs are excellent systems to study and analyze the complex hysteretic and reversal mechanisms of ferromagnets. ,− …”
