摘要
We present some universal results for exchange springs in multilayer systems with alternating hard and soft layers. In particular, the reduced magnetisation <cos theta>, for both symmetric exchange springs (0-->phi-->0) and 180degrees exchange springs (0-->pi), is given in terms of elliptic functions. The result for the symmetric exchange spring is found to be in good accord with experimental results on MBE grown DyFe2/YFe2 multilayers. (C) 2002 Elsevier Science B.V. All rights reserved.
