Abstract

The exchange coupling behavior of the epitaxial Nd-Co(11̄00)/Sm-Co exchange-spring bilayers was analyzed. The magnitude of the exchange field H_ex was found to increase when temperature was increased from 300 to 350 K, which was due to the temperature dependent magnetic anisotropy of the Nd-Co layer. The results show that the maximum size of the soft phase for the effective exchange-spring coupling can be enhanced by tailoring the magnetic anisotropy of the soft phase.
