Magnetic Behaviors of Arrays of Co-Ni-P Nanorod: Effects of Applied Magnetic Field

抄録

The Co-Ni-P nanorods were fabricated by electrodeposition method by using the porous polycarbonate template. The investigation by mean of X-ray diffraction and high-resolution transmission electron microscopy indicated that samples were nanocrystalline clusters embedded in the amorphous base. The samples exhibited a room temperature ferromagnetism with the high magnetic anisotropy along the rod. The applied magnetic fields during the fabrication of the Co-Ni-P nanorods was strongly influenced by the magnetic properties. The M_R/M_S ratio and coercivity rapidly increased when the magnetic applied field changed from 0 to 0.21 T.
