Abstract
Sm22Co78/Fe/Sm22Co78 trilayers with 30% volume fraction of Fe layer were de posited on Cr/glass substrates by magnetic sputtering. All the samples have in-plane anisotropy and their hysteresis loops were single-phase types, in dicating that the two phases exhibit strong exchange coupling. The reduced remanence of the trilayer system is significantly increased with the increa sing thickness of Fe layer (d), the coercivity of the trilayer also increas ed for the layer with d < 40 nm. and have a maximum value at 13 nm for 30% volume fraction of Fe layer. The magnetic interaction studies indicated tha t positive and negative exchange couplings were different for different d v alues. (C) 2001 Elsevier Science B.V. All rights reserved.
