In the field of nanomagnetism and its techno-logical 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.2021http://zaguan.unizar.es/record/9972810.3390/nano11020402http://zaguan.unizar.es/record/99728oai:zaguan.unizar.es:99728info:eu-repo/grantAgreement/ES/DGA-FEDER/Construyendo Europa desde Aragóninfo:eu-repo/grantAgreement/ES/DGA-FSE/E13-20Rinfo:eu-repo/grantAgreement/EC/H2020/823717/EU/Enabling Science and Technology through European Electron Microscopy/ESTEEM3This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 823717-ESTEEM3info:eu-repo/grantAgreement/ES/MINECO-FSE/BES-2015-072950info:eu-repo/grantAgreement/ES/MINECO/MAT2017-82970-C2-1-Rinfo:eu-repo/grantAgreement/ES/MINECO/MAT2017-82970-C2-2-RNanomaterials 11, 2 (2021), 402 [20 pp]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
