【 摘 要 】

The basic problem of a single hole in a magnetic film with uniaxial anisotropy has been analyzed in detail by magnetic force microscopy, micromagnetic simulations, and an analytical model. The closure magnetization configuration can be described by two -1/2 half vortices located at the hole edge along the easy anisotropy axis and confined within a distance L that is determined by the minimization of magnetostatic and anisotropy energies constrained by the magnetic charge conservation within the system.
