Diffusion-limited aggregation at multiple centers: Model of dendrite growth at ion beam synthesis of magnetic films in external field
چکیده انگلیسی

Computer simulations are used to generate two-dimensional dendrites from atoms carrying magnetic moment being parallel to the external magnetic field. The numerical model is based on the model of diffusion-limited aggregation at multiple centers. The magnetic dipole–dipole interaction between diffusing implanted atoms and growing ferromagnetic dendrites is taken into account. It is shown that magnetically induced anisotropy of grown dendrites follows to elongation of them in external field direction. The process of growth of these dendrites is analyzed by measuring mean relative elongation versus number of deposited particles within the grid.


► Description of dendrites growth at ion beam synthesis using numerical model.
► Computer model based on Multicenter DLA, but with magnetic interactions.
► Estimation of relative elongation of growing dendrites.
► Estimation of effective look up radius for probabilities calculation.
