abstract = {We have investigated the impact of out-of-plane
ferromagnetic (FM) anisotropy (which can be coincident with
the direction of unidirectional anisotropy), where
antiferromagnetic (AF) anisotropy is along the film plane.
This provides a platform for non-collinear exchange coupling
in an archetypal exchange coupled system in an
unconventional way. We probe the in-plane magnetization by
the depth-sensitive vector magnetometry technique. The
experimental findings reveal a magnetization reversal (i)
that is symmetric for both the branches of the hysteresis
loop, (ii) that is characterized by vertically correlated
domains associated with a strong transverse component of
magnetization and (iii) that remains untrained (suppression
of trained state) with field cycling. This scenario has been
compared with in-plane magnetization reversal for a
conventional in-plane unidirectional anisotropic case in the
same system that shows usual asymmetric reversal and
training for vertically uncorrelated domains. We explain the
above observations for the out-of-plane case in terms of
inhomogeneous magnetic states due to competing perpendicular
anisotropies that result in non-collinear FM–AF coupling.
This study provides direct evidence for the vertical
correlation of domains mediated by out-of-plane exchange
coupling},
