Abstract:
The magnetic structure of thin nanocrystalline films with a random distribution of magnetization easy axes was studied by means of micromagnetic modeling. The dependences of the correlation function parameters of the non-uniform magnetization on the value of the external in-plane magnetic field were investigated in the wide range (6–1000 nm) of particles sizes. An analysis of the obtained dependences revealed a significant difference between longitudinal (along the field) and transversal (perpendicular to the field) correlation radii of a stochastic magnetic structure. The blocking effect of a fine magnetic structure—a magnetization ripple—was observed during magnetization reversal of the films.
