Present and future applications of magnetic nanostructures grown by FEBID

Currently, magnetic nanostructures are routinely grown by focused electron beam induced deposition (FEBID). In the present article, we review the milestones produced in the topic in the past as well as the future applications of this technology. Regarding past milestones, we highlight the achievement of high-purity cobalt and iron deposits, the high lateral resolution obtained, the growth of 3D magnetic deposits, the exploration of magnetic alloys and the application of magnetic deposits for Hall sensing and in domain-wall conduit and magnetologic devices. With respect to future perspectives of the topic, we emphasize the potential role of magnetic nanostructures grown by FEBID for applications related to highly integrated 2D arrays, 3D nanowires devices, fabrication of advanced scanning-probe systems, basic studies of magnetic structures and their dynamics, small sensors (including biosensors) and new applications brought by magnetic alloys and even exchange biased systems.This work was supported by Spanish Ministry of Economy and Competitivity through project No. MAT2011- 27553-C02, including FEDER funds, by the Aragón Regional Government, by the I-LINK0026 project funded by the Spanish CSIC and by a Marie Curie Intra European Fellowship project No. 251698: 3DMAGNANOW, funded by the 7th European Community Framework Programme.Peer Reviewe
