The Research Of Metal Magnetic Line Arrays By Ultra-thin Electrochemical Deposition

The main work of this paper, is based on past laboratory work, nanostructured copper filaments in electrochemical deposition, in such a freezing system, to realize preparation of cobalt and iron filaments by electrochemical deposition.Main research content includes:1. We found that when the width change from large to small, the magnetic domain wall of the smooth cobalt filaments, would display the distribution from random stripe to parallel stripe, then to alternately and oppositely arranged. We recognize the periodic concave-convex structure as a geometric restriction, find that it will affect the magnetic structure of cobalt filaments with magnetic interactions.2. In our quasi two-dimensional system, we obtained iron filaments with the glass substrate, simultaneously observed a periodic nanometer structure. However, we did not obtain the regular domain structure as the cobalt filaments.
