Abstract  Direct current electro-deposition was applied to add Nickel to the nano-scale holes of porous Alumina template prepared by two-step anodic oxidation. The structure and magnetic performance of Ni-Al2O3 array system were investigated by electron microscope, X-Ray and vibration sample magnetometer. The results indicated that the regularity of the holes’ arrangement in the porous Alumina membrane by two-step anodic oxidation was obviously better than that by one-step anodic oxidation. Nickel was in single crystal state in the nanochannal array system and had definite crystall selective-orientation. The array had obvious magnetic anisotropy, and was promising for perpendicular magnetic recording medium.
