Abstract:Permalloy can exhibit magnetic vortex configurations depending on their dimensions and geometry, being of great interest due to potential applications in data storage and for cancer treatment. This work focuses on the effects of perpendicular uniaxial anisotropy, dimensions of permalloy nanodisks, and magnetostatic interactions on the annihilation and nucleation fields of magnetic vortices by means of micromagnetic simulations. Nanodisks with different diameters were evaluated, considering the effect of anisot… Show more
