Abstract
The magnetization measurement for annealed Co(6 Angstrom)/Cu(14 Angstrom) x 15 multilayers, evaporated on Si (1 1 1) substraie, showed easy direction parallel to the film. The in-plane DC demagnetization remanence curve has a minimum with amplitude much higher than the saturation remanence for magne tic field applied perpendicular to the easy axis. This is explained as caus ed by a portion of the sample, having negative remanence. (C) 1999 Elsevier Science B.V. All rights reserved.
