Figure 5From: Magnetic anisotropy in isotropic and nanopatterned strongly exchange-coupled nanolayersMagnetic hysteresis loops along the easy (red) and hard (blue) magnetisation directions. The samples consist of an increasing number of (Co8 nm-54°/Co12 nm-0°/Ta6 nm-54°) trilayers: one to four trilayers plotted in (a) to (d), respectively.Back to article page
