摘要：
[Nd-Fe-B(x nm)/FeMn(d nm)](n) thin films were deposited by magnetron sputtering on Si (100) substrates heated at 650 degrees C. The influence of the composition and thickness of FeMn layer on the structure and magnetic properties of Nd-Fe-B films are investigated. The Nd-Fe-B/FeMn multilayer films present an enhanced coercivity and a reduced saturation magnetization, in comparison with those of a Nd-Fe-B single layer. The coercivity of [Nd-Fe-B(x nm)/FeMn(5 nm)](n) films increases with increasing the period number of FeMn layer for the same thickness of magnetic layer, while the coercivity in [Nd-Fe-B(50 nm)/FeMn (5 nm)](n) films increases with decreasing the period number of Nd-Fe-B/FeMn bilayers. The coercivity H-c of about 17.2 kOe is achieved in the Nd-Fe-B(50 nm)/FeMn(5 nm) film. (C) 2009 Elsevier B.V. All rights reserved.
