摘要：

Cobalt nanowires have been electrodeposited into the pores of polycarbonate membranes. Through the comparison of two kinds of samples fabricated without magnetic field and with 1.2 X 10(4) A/m magnetic field,respectively, the influence of magnetic field on the structure of electrodeposited Co nanowires has been investigated. Combined with transmission electron microscopy,X-ray diffraction and vibrating sample magnetometer measurements,we found that the samples deposited under magnetic field form texture, therefore exhibit uniaxial magnetic anisotropy, and the coersivity (H-c) and squareness (M-r/M-s) were greatly enhanced.
