Time Dependence of the Magnetic After Effect in Co/Pd Multilayer Thin Films

Abstract: The magnetic after effect was explored in Co/Pd multilayer thin films with a magnetization perpendicular to the film plane using the Extraordinary Hall Effect (EHE). The voltage due to the EHE measures the net magnetization perpendicular to the plane of the film; the sign of the voltage changes from an up to down magnetization orientation relative to the film plane. It was found that at applied fields when the magnetization of the Co/Pd sample was flipping its magnetization from up to down, the EHE voltage varied with time as a quasi-logarithm of time. These measurements were made at multiple magnetic fields in the regime when the magnetization was flipping. Download poster. [PDF]
