31/12/2019 · One dimensional nanowires are especially shown prospects in miniaturization of devices. In nanowires geometry, two directions are confined to nanoscale whereas the third dimension is unconfined. The magnetic properties of nanowires are strongly affected by its high aspect ratio, finite size effects and shape anisotropy. 12–14 12. J. U.
high energy ballmilling technique49 or a chemical vapour phase transport method43 carried out at high temperature and complex reaction conditions, and the resulting product morphology was difficult to control.
