Abstract
Magnetoresistance (MR), extraordinary Hall effect (EHE), planar Hall effect (PHE), and low-frequency noise are measured on pseudospin-valves based on Co/Pd multilayers with perpendicular magnetic anisotropy. In unpatterned films, a current-in-plane MR of 3.8% was obtained with a Cu spacer layer thickness of 2.0 nm. Large anomalous peaks observed in EHE and PHE in the narrow range of field where switching occurs are associated with multidomain magnetization during the reversal process. Magnetic field-and time-dependent noise indicates that the magnitude of the noise is directly related to magnetization switching in this system.
