Microstructure and Magnetic Behavior of One-Dimensional Co_0.5Zn_0.5Fe₂O₄ Nanofibers

Abstract:

One-dimensional Co_0.5Zn_0.5Fe₂O₄ nanostructures (nanofibers) with an average diameter of 154 nm were fabricated by electrospinning. These nanofibers were characterized by X–ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy. Magnetic hysteresis loops were measured for randomly oriented and aligned Co_0.5Zn_0.5Fe₂O₄ nanofibers, in comparison with the corresponding powder sample synthesized using the conventional sol-gel process. The differences in magnetic properties are observed between the Co_0.5Zn_0.5Fe₂O₄ nanofibers and powders, and these differences mainly arise from the grain size and morphological variations between these two materials. In determining the magnetization ease axis for the aligned Co_0.5Zn_0.5Fe₂O₄ nanofibers the shape anisotropy is slightly dominant competing with the magnetocrystalline anisotropy.
