We present some universal results for exchange springs in multilayer systems with alternating hard and soft layers. In particular, the reduced magnetisation cos θ, for both symmetric exchange springs (0 → π) and 180° exchange springs (0 → φ → 0), 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.

Abstract

We present some universal results for exchange springs in multilayer systems with alternating hard and soft layers. In particular, the reduced magnetisation cos θ, for both symmetric exchange springs (0 → π) and 180° exchange springs (0 → φ → 0), 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.
