|Abstract:||Axial magnetization processes in soft ferromagnetic nanodots are investigated in this paper. Under the simplifying assumption of axisymmetric vortex-like magnetic structures we find the equilibrium magnetic configuration by unidimensional numerical minimization of the magnetic Gibbs free energy. We propose a simple analytical model for the axial magnetization processes in amorphous ferromagnetic nanodots. Axial coercive field values from this analytical model are compared with those from full numerical micromagnetic simulations and good agreement is obtained. An experimental method for evaluating the exchange interactions in soft magnetic materials by using the axial magnetic loops of nanodots with different aspect ratios is proposed.
