Abstract

Model calculations and micromagnetic simulations were used to analyze the magnetic ground state and the magnetization reversal of aspherical nanoparticles. There were no domains in the dots at the lower end of the size and thickness range. The large particles were multidomain with complete flux closure and complex reversal behavior. The results show that the magnetostatic self interactions in real elongated particles were much stronger than those in ellipsoidal particles because in ellipsoidal particles the surface charges were quite delocalized.
