Ferromagnetic anisotropy of carbon-doped ZnO nanoneedles fabricated by ion beam technique
چکیده انگلیسی

Carbon-doped ZnO (ZnO:C) nanoneedles were fabricated using ion beam irradiation with a simultaneous supply of carbon at room temperature. The structure and the magnetic properties of the ZnO:C nanoneedles were investigated. Hysteresis loops and zero-field cooling (ZFC) and field cooling (FC) curves demonstrated the ferromagnetic properties of the ZnO:C nanoneedles. The Curie temperature of the ZnO:C is above 330 K. The ferromagnetic anisotropy with an easy axis perpendicular to the shape axis of the ZnO:C nanoneedles was observed due to the dipole-dipole magnetic interaction amongst nanoneedles.

► We report the ferromagnetic anisotropy of carbon-doped ZnO (ZnO:C) nanoneedles. ► The anisotropy of the ZnO:C was studied using the dipole-dipole interaction model. ► The ferromagnetic anisotropy with an easy axis perpendicular to the shape axis of the ZnO:C nanoneedles.
