|Abstract:||A simple method for determining the chirality of magnetization vortex in Co dots based on planar Hall effect (PHE) has been demonstrated. We detected different PHE signals associated with the direction of vortex propagation for magnetization vortices with opposite chiralities when a Co dot of diameter d=1 μm and thickness t=40 nm was placed off the center of a Hall junction. We observed that the magnitude of the voltage jump at the annihilation field is directly related to the chirality of the vortex. Our experimental results are in good agreement with a simple theoretical modeling using finite element analysis. The simulation shows ∼10% relative voltage change between vortices of opposite chiralities for d=1μm and ∼200% relative voltage change for d =150 nm. © 2006 American Institute of Physics.|
