Abstract:	We experimentally and theoretically demonstrate that the abrupt change in magnetostatic energy during the free and pinned [Co/Pd] layer reversal by an external magnetic field and the magnetic field dependent extraordinary Hall effect (EHE) coefficient are the main physical reasons for the anomalous peaks observed in EHE measurement of exchange biased [Pd/Co]/Cu/Co/[Pd/Co]/FeMn giant magnetoresistance spin-valves with perpendicular anisotropy (EBPA-SVs). The correlation of the anomalous EHE peaks to the extrinsic magnetic properties of EBPA-SVs paves a way to indirectly evaluate these properties. © 2011 American Institute of Physics.
