Study of magnetization process in Co-Cr-Ta media and Co/Pt multilayered media by Anomalous Hall effect analysis

Abstract

Magnetic interaction as well as magnetization process in the Co-Cr-Ta media and Co/Pt multilayered media under the canted magnetic field have been investigated by using the Anomalous Hall effect measurement. ΔM plot has been calculated from the initial curve and the hysteresis curve of the samples to evaluate the interaction among the magnetic particles. Magnetic field was applied in the direction from the normal to in-plane direction. Co-Cr-Ta thin film exhibited the magnetic interaction depending on field direction while the magnetic interaction in the Co/Pt multilayered thin film remained unchanged though the magnetic field direction was changed.
