抄録

The [Sm (Co,Cu)5 Fe]6 multilayer film that was fabricated by annealing Cr [a- (Sm-Co) (9 nm) Cu (x nm) Fe (5 nm) Cu (x nm)] 6 Cr (x=0-0.75) multilayer has shown good in-plane texture and a high maximum energy product (BH)max of 32 MGOe with a coercivity of 7.24 kOe. The addition of the Cu layer between the a-d-SM- Co6 and Fe layers with optimum thickness increases the coercivity significantly, thereby improving the maximum energy product. The single-phase behavior and the irreversible rotation in the demagnetization process indicates strong exchange coupling between the Sm (Co,Cu)5 and Fe layers.
