Abstract:
Magnetization and magnetostriction data are reported for discontinuous type exchange-spring
Tb(Fe0.55Co0.45)1.5/(Y 0.1Fe0.9) multilayers, in which nanograins coexist with amorphous phase in soft
YFe layers. This novel exchange-spring configuration exhibits an excellent magnetic and magnetostrictive
softness: low magnetic coercivity (?0HC=1mT), large magnetostriction (???,2= 720??10-6) and large
parallel magnetostrictive susceptibility (???||;=d?||/d?0H=29. 7??10-2T-1). In addition, the observed
phenomena of the negative contribution to magnetostriction, the formation of the extended domain wall at
the interfaces and the exchange-bias are discussed. ?? 2004 Elsevier B.V. All rights reserved.
