“…4), we suggest that the out-ofplane magnetic anisotropy observed in most of our samples most likely comes from the formation of CoPd alloys at the interface between Co and MnPd layers. This assumption is consistent with the previous studies on out-of-plane magnetic anisotropy in Co/Pd multilayers [15,16]. These alloys are known to have extremely large negative magnetostriction constants and can experience significant tensile in-plane strains due to the lattice mismatch with MnPd layers in the multilayers leading to the out-of-plane orientation of the FM magnetization.…”

“…23,24 Experimentally, it is challenging to distinguish the two mechanisms, because of the complexity at the interfaces. 25,26 Rapid thermal annealing, which induces interface diffusion, should not only significantly modify the M, anisotropy, and longitudinal resistivity but also AHE, if AHE is dominated by interface scattering in the multilayers. Indeed, such a correlation among M, longitudinal resistivity, and AHE has been observed in our experiment.…”

“…Variations associated with the grain structure certainly could be responsible as grain sizes are typically in the range 5-20 nm. The local variation in anisotropy could also be a result of variations in stress, for example, Hong et al [19] recently proposed that stressed interfacial alloying played an important role in creating perpendicular anisotropy in Co=Pd multilayer films. While the exact nature of the underlying source of the intrinsic anisotropy distribution remains to be fully explained, the ability to accurately characterize it using the methods demonstrated has wide application in nanomagnetic systems.…”
