The fabrication of multi-component polycrystalline or granular metals by FEBID represents a challenging research approach for the design of novel nanostructured materials. Currently, there are three different approaches for the fabrication of multi-component FEBID nanostructures: 1. deposition by single source heteronuclear precursors; 2. codeposition using two different precursors; 3. intermixing of multilayer nanostructures fabricated with different precursors by low-energy electron irradiation. These fabrication approaches allow the fabrication of a large number of tunable alloy nanostructured and intermetallic compounds. In this contribution, we present some examples of binary and ternary nanostructures fabricated by following these routes. In particular, we report on the fabrication, the structural characterization and magnetotransport measurements of CoFe alloys and Co2FeSi Heusler compounds.
