The investigation with a n electron microscope,an X-ray diffractmeter and a vibration sample magnetomete r indicates that the Ni nanowires, growing in the pores of AAM with about 45nm i n diameter, are monocrystalline and have a definite preferred crystallizing orie ntation. The magnetic behavior of the arrays and their mechanism were discussed.展开更多
