摘要
Nd-Fe-B films were prepared by DC magnetron sputtering and the effect of buffer layer and annealing conditions on the magnetic properties have been investigated. High degree of texture, highest coercivity and energy product are achieved in Ta-buffered films deposited on heated substrates. A linear increase of coercivity with film thickness up to 10 mm is observed. (C) 2004 Elsevier B.V. All rights reserved.
