Abstract :
Summary form only given. Magnetic switching processes in patterned nanosquares have been studied for different in-plane applied field angles by means of micromagnetic computations. This systematic study was carried out without taking into account the effect of thermal activation. In order to investigate the effect of temperature on the angular dependence of coercivity in these nanostructures, a stochastic three-dimensional zero-mean gaussian field is introduced in the Landau-Lifschitz-Gilbert equation. The corresponding Langevin equation is solved using a first order Euler scheme and the Stratonovich interpretation.
