Abstract
Co100−xPtx alloy thin-films were produced to investigate structural transformation during thermal annealing and ensuing magnetic properties of the thin films. Maximum coercivity of 7000 Oe was obtained with Co61Pt39 annealed at 700 °C due to precipitation of the CoPt intermetallic compound. We also observed the exchange coupling between Co and CoPt and the composite film acted as a single phase system despite consisting of Co and CoPt grains. (© 2004 WILEY-VCH Verlag GmbH & Co.
