Abstract
We have carried out polarised neutron reflectivity (PNR) and switching fiel d distribution (SFD) measurements on both a single 60 nm CoCrPt film and a similar film bisected by a 5 nm spacer of Cr. The PNR data from the single film show that reversal can be understood in terms of a simple switching me chanism. That of the bisected film is more complex with two distinct quasi- independent switching processes. Moreover, the depth dependence of the neut ron signal has allowed us to correlate each switching event with a particul ar layer. The switching behaviour is explained in terms of the film microst ructure. (C) 1999 Elsevier Science B.V. All rights reserved.
