The fitting of demagnetization curves to simple Neel Arrhenius model, using the volume distribution, suggests that in I non-interacting case one Monte Carlo step is proportional to a square root of time. The same dependence arises from the consideration of magnetic particle moving in the external potential according to Brownian dynamics. This constitutes the basis of the so-called Monte Carlo With quantified time step The analytical calculations show that the method works reasonably in the case of small-to-intermediate size barriers and for a high anisotropy system. The application of the method to magnetic recording media reveals qualitatively the same dependence on the exchange parameter as Obtained by kinetic Monte Carlo.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S0304885301013555http://www.sciencedirect.com/restricted access530.1Micromagnetic calculationsThermal stabilityFísica matemática
