Probing the Magnetization Reversal of Microstructured Permalloy Cross by Planar Hall Measurement and Magnetic Force Microscopy

A local magnetization reversal of Permalloy cross has been studied by using magnetoresistance measurement and magnetic force microscope. An extraordinary change of the transverse voltage correlated with the planar Hall Effect was presented and evidenced by a series of MFM images which indicates that the rotation of magnetization within the joint area contributes to the significant voltage alteration
