Abstract
Single-phase, near stoichiometric X-type Fe2CoGa nanowires with an average diameter of 253 ± 2 nm have been synthesized using the electrospinning route. The highly ordered polycrystalline nanowires with a lattice constant of 5.758 Å demonstrated ferromagnetic behaviour, with a substantial saturation magnetization of 4.61 μB f.u.−1 at 5 K and a high effective anisotropy constant of ∼9.36 × 106 erg cc−1 at 5 K. The electronic density of states near the Fermi level, estimated using ab initio calculations, provides insight into the electronic behaviour of this compound. These findings highlight the potential of ferromagnetic Fe2CoGa nanowires for nanomagnetic devices and magnetic data storage, and a scalable and versatile approach for fabricating nanoscale Heusler alloys via the electrospinning route.Keywords
