Abstract
The magnetic vortex chirality is determined using lateral spin valve geometry fabricated by means of conventional lift-off technique. In the ferromagnetic disk structure, magnetization reversal occurs through the nucleation and annihilation of the vortex. The magnetization processes of the disk is studied by measuring the planar Hall effect (PHE) and the non-local spin-valve (NLSV) measurements are performed.
