АннотацияThe magnetization reversal processes in thin obliquely deposited films were studied by means of micromagnetic 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 α. The results showed that for films with α < 65◦ 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 quasidomain magnetic structures. The numerical results are in a good accordance with the previously reported experimental measurements

[2]), to our knowledge, only a few theoretical works are present [6, 7]. <...> In this work, we use Monte Carlo film growth simulator ∗platon.solovev@gmail.com <...>
