Magnetically Anisotropic Cobalt and Iron Nanofibers via Electrospinning

Magnetically anisotropic cobalt and iron nanofibers (see figure) are obtained via oriented polymer‐supported electrospinning and subsequent reduction and thermal treatment. The cobalt and iron nature of the fibers is confirmed by XRD analysis. Fibers of both metals show ferromagnetic behavior. Paral...

Description
Summary:Magnetically anisotropic cobalt and iron nanofibers (see figure) are obtained via oriented polymer‐supported electrospinning and subsequent reduction and thermal treatment. The cobalt and iron nature of the fibers is confirmed by XRD analysis. Fibers of both metals show ferromagnetic behavior. Parallel aligned iron nanofibers revealed anisotropic hysteresis loops depending on field‐fiber orientation.
