“…Core-shell NWs comprising different core and shell materials can offer the advantage of combined properties from more than one material to convey multi-functional capabilities 14 15 . Tailoring the magnetic properties was successfully achieved in various sensor applications in core-shell metallic micro and nanowires 16 17 . Hybrid metallic/non-metallic nanowires offer specific advantages.…”

We have synthesized nanowires with an iron core and an iron oxide (magnetite) shell by a facile low-cost fabrication process. The magnetic properties of the nanowires can be tuned by changing shell thicknesses to yield remarkable new properties and multi-functionality. A multi-domain state at remanence can be obtained, which is an attractive feature for biomedical applications, where a low remanence is desirable. The nanowires can also be encoded with different remanence values. Notably, the oxidation process of single-crystal iron nanowires halts at a shell thickness of 10 nm. The oxide shell of these nanowires acts as a passivation layer, retaining the magnetic properties of the iron core even during high-temperature operations. This property renders these core-shell nanowires attractive materials for application to harsh environments. A cell viability study reveals a high degree of biocompatibility of the core-shell nanowires.

Amorphous magnetic metals are being investigated because of their outstanding magnetic behavior that makes them especially suitable as sensing elements in various devices [1]. Their particular magnetic behavior is a consequence of the intrinsic atomic disordering that in addition results in very interesting fundamental phenomena. Glassy metals are prepared by rapid solidification techniques that enable their preparation in planar (ribbons or thin films [2]) or cylindrical (wires) shapes [3]. Alternatively, amorphous alloys with interesting magnetic behavior can be also obtained as bulk material or can give rise to ultrasoft magnetic alloys after
