Abstract

We have used the planar Hall effect (PHE) with the applied field perpendicular to the surface of the plane in order to investigate the perpendicular anisotropy of a thin Co film. To characterise the perpendicular anisotropy we measured the field dependence of the PHE at a fixed angle and the angular dependence of the PHE at a fixed field. The latter dependence was fitted using a single-domain model. The effective perpendicular anisotropy was extracted and compared with that extracted by fitting torque measurements on the same film.
