Magnetic properties and interface scattering contribution to the anomalous Hall effect in cobalt / palladium multilayers

Abstract (Summary)

[Co/Pd]n multilayers with different number of repetitions n were deposited on Si substrates in order to study the magnetic properties and Hall resistivity in this system. The magnetic moment dependence on applied field was studied in parallel (in-plane) and perpendicular (out-of-plane) configurations. The [Co/Pd]n multilayers with 2 and 3 repetitions, with thickness of the Co sublayer of 0.8 and 1.0 nm and thickness of the Pd sublayer of 1.3 and 2.0 nm, were found to have perpendicular magnetic anisotropy. The Hall resistivity dependence on applied field was measured at different temperatures. The Hall hysteresis loops confirm the perpendicular anisotropy of the multilayers, and indicate that the origin of the anomalous Hall effect (AHE) in this system, with low number of repetitions, is dominated by surface scattering.
