摘要：

Arrays of Nd5Fe95-xBx (17 <= x <= 28) nanowires were fabricated by electrodepositing in pores of anodic aluminum oxide (AAO) templates. Transmission electron microscope result shows that the nanowires are about 40 nm in diameter and the aspect ratio is approximately 75. Selected area electron diffraction and X-ray diffraction results indicate that the nanowires are amorphous in structure at concentration x=25. Vibrating sample magnetometer was employed to study the magnetic properties of nanowire arrays at room temperature. Due to the shape anisotropy effect, the arrays of nanowires exhibit obviously uniaxial magnetic anisotropy and the easy magnetizing axis is parallel to the nanowires. The coercivity with the magnetic field along the nanowire arrays decreases with the increasing of the B content. (c) 2008 Elsevier B.V. All rights reserved.
