In-plane bias in a patterned ferromagnetic/antiferromagnetic bilayer



Yury P. Kabanov, Valerian I. Nikitenko, Oleg A. Tikhomirov, William F. Egelhoff Jr., Alexander J. Shapiro, Robert D. Shull


Exchange bias in bi- and multilayer magnetic systems is usually ascribed to the existence of transient magnetic structures at the interfaces between adjacent layers. Here, we report the observation of a similar phenomenon in the lateral direction, indicated by an asymmetry in the magnetization reversal of a ferromagnetic film covered with a square grid of an antiferromagnetic layer. A canted orientation of the intrinsic anisotropy of the ferromagnet with respect to an induced exchange anisotropy and the presence of artificial stationary domain walls are discussed as likely origins of the effect.
