摘要
Experimental results are presented for several exchange-coupled nanocrystalline alloys of composition Sm-18(Fe,Co)(82) with different Fe contents. Minor loops, Henkel plots, and recoil curves are shown to be in excellent agreement with calculations performed using the moving Preisach model (MPM). Experimental reversible and irreversible magnetization components are found to be in excellent agreement with MPM simulations. (C) 1999 Elsevier Science B.V. All rights reserved.
