Abstract
The ferromagnetic coupling across Pd interlayers has been determined from hysteresis loop measurements on multilayers of the type M3/8 Å Ru/M2/χPd/M1. Here M1, M2 and M3 denote magnetic layers consisting of (strongly ferromagnetically coupled) Co/Pd multilayers with perpendicular magnetic anisotropy. The hysteresis loops displayed a staircase behavior. Analysis of the steps yielded coupling values between 0.17 mJ/m2 (at 14 Å Pd) and 0.02 mJ/m2 (at 20 å Pd).
