“…However, the influence of the MFM tip over the stability of the configuration is not yet clear. For further experiments addressing this topic, lower moment MFM tips were designed and characterized 44,45 (see Table 1 and ESI6 † for more details), which give us a gradient of tip stray fields with tuned intensity.…”

“…Both as-grown and annealed nanowires present a surface with much lower metallic content due to natural oxidation or accumulation of residual carbon contaminants upon thermal annealing. This is more critical in FEBID Fe, which tends to produce much thinner nanowires-down to 35 nm in diameter [24]-than in FEBID Co. While in a 100 nm-wide 3D Co nanowire, a 5 nm-thick degraded surface represents 19% of the total volume; in a 3D Fe nanowire with a typical diameter of 50 nm, it scales up to 36%.…”

“…In particular, the growth of 3D ferromagnets by FEBID has been fruitful and yielded highly sophisticated architectures. Remarkable applications have been developed in magnetic sensing by functionalization of magnetic probes for magnetic force microscopy [22] and ferromagnetic resonance force microscopy [23] in materials science and biology [24], as magnetically driven mechanical nano-actuators [25], 3D domain wall conduit [26], ferromagnetic designs based on 3D FEBID scaffolds [18], arrays of 3D nanopillars for magnetic logic [27], 3D artificial ferromagnetic lattices [28,29], and magnetically chiral 3D architectures [30]. Further examples of applications of 3D FEBID ferromagnets have been reviewed recently by Fernández-Pacheco et al [31].…”

Focused-electron-beam-induced deposition (FEBID) is the ultimate additive nanofabrication technique for the growth of 3D nanostructures. In the field of nanomagnetism and its technological applications, FEBID could be a viable solution to produce future high-density, low-power, fast nanoelectronic devices based on the domain wall conduit in 3D nanomagnets. While FEBID has demonstrated the flexibility to produce 3D nanostructures with almost any shape and geometry, the basic physical properties of these out-of-plane deposits are often seriously degraded from their bulk counterparts due to the presence of contaminants. This work reviews the experimental efforts to understand and control the physical processes involved in 3D FEBID growth of nanomagnets. Co and Fe FEBID straight vertical nanowires have been used as benchmark geometry to tailor their dimensions, microstructure, composition and magnetism by smartly tuning the growth parameters, post-growth purification treatments and heterostructuring.

“…The main purpose of this review is to compile and describe the most recent applications based on NWs. Although there are several techniques to grow NWs such as using few nanometer-diameter nuclear-track etched polymer templates [8], growing them individually using Focused Electron Beam Induced Deposition (FEBID) [10] and directly released in solution using soft, polyol or organometallic chemistry [11], to name a few, we will limit our considerations to those works, in which the NWs were fabricated by electrochemical deposition into alumina templates. This last-mentioned method provides a large control over parameters in combination with many degrees of freedom for tailored designs.…”

Cylindrical magnetic nanowires feature unique properties, which make them attractive for fundamental research as well as novel applications. These one-dimensional structures introduce a pronounced shape anisotropy that together with material selection can strongly affect the magnetic properties and can be tuned by incorporating segments of different materials or diameters along the length. They attract a large interest in the scientific community, ranging from physicists to material scientists to bioengineers. Consequently, these nanowires are developed for and employed in very diverse applications in medicine, biology, data and energy storage, catalysis or microwave electronics, among others. In this review we investigate the most active emerging applications of cylindrical nanowires grown in alumina templates by electrochemical deposition. This method has several key features, including low cost and a high level of control over the design. A fundamental property that distinguishes those applications is the operating frequency, which we chose to apply as an underlying structure for this review. With this we attempt to provide a wide and organized view of applications based on cylindrical magnetic nanowires with a focus on tailored physical and chemical properties.
