Micromagnetic Simulation of Magnetization Reversal Processes in Thin Obliquely Deposited Films

Abstract

The magnetization reversal processes in thin obliquely deposited films were studied by means of micro- magnetic modeling. Thin film structures for micromagnetic study were generated by Monte Carlo film growth simulator. Using obtained hysteresis loops for the generated films, we retrieved coercivity and remanent magnetization as a function of the deposition angle alpha. The results showed that for films with alpha<65 degr. the magnetization reversal occurred via coherent rotation of magnetic moments, whereas samples generated with larger deposition angles reverse their magnetization by the formation of complex quasi- domain magnetic structures.
