Change in planar hall effect ratio of Ni-Co films produced by electrodeposition

Abstract

Ni-Co Films were produced by the electrodeposition technique and their magnetotransport properties were studied. The anisotropic magnetoresistance (AMR) and the planar Hall effect (PRE) ratios were Found using the van der Pauw setup at room temperature. It was observed that the ORE ratios were larger than the obtained AMR ratios. While the maximum changes in longitudinal and transversal magnetoresistance ratios were 6.8% and 140%, respectively, the change in ORE values was up to 500%. In the ORE measurements, the magnetoresistance orientation depends on the electrical resistance values which occur in branches of the films.
