摘要	A magnetic heat treatment is employed for [Sm-Co (21 nm)/Fe65Co35 (7 nm)](10) multi-layered films prepared by magnetron sputtering. It is found that applying magnetic field along the plane of films during annealing (magnetic heat treatment) is favorable for enhancing the coercivity of the films, compared with annealing under no field. The exchange interaction is analyzed in detail by measuring the remanence magnetization. The contribution of the exchange interaction to the magnetic reversal can be deduced from the deltam curves and the annealing temperature dependence of coercivity. Additionally, the magnetic viscosity studies reveal that the magnetic heat treatment improves the stability of magnetic properties of the films. (C) 2003 Elsevier B.V. All rights reserved.
