Abstract

The galvanomagnetic effect in a polycrystal Co thin film was investigated by measuring magnetoresistance and Hall resistance. The observed magnetoresistance can be understood in term of the anisotropic magnetoresistance effect using the Stoner-Wohlfarth model. The observed Hall resistance cannot be explained syfficiently by the planar Hall effect using the Stoner-Wohlfarth model. In order to explain the observed Hall resistance, we took the exchange interaction from the current and voltage probes into consideration and numerically calculated the magnetoresistance and the Hall resistance. The calculated results obtained using this model are in reasonable agreement with the experimental results.
