Dynamical properties of magnetization reversal in an ultrathin Au/Co film
We present a dynamical study of hysteresis loops of a MoS sub 2 /[Au/Co/Au] sandwich performed by surface magneto-optical Kerr effect with a field variation rate up to 1.2 MOe/s. An interpretation of dynamical effects at room temperature is proposed, using a modelization of the magnetization reversa...

| description | We present a dynamical study of hysteresis loops of a MoS sub 2 /[Au/Co/Au] sandwich performed by surface magneto-optical Kerr effect with a field variation rate up to 1.2 MOe/s. An interpretation of dynamical effects at room temperature is proposed, using a modelization of the magnetization reversal. We discussed simulations which describe two different processes of the magnetization reversal to interpret the evolution of the hysteresis loops for several rates of variation of the magnetic field. For a first range of field variation rates < 180 kOe/s, the predominant mechanism seems to be wall motion and beyond 180 kOe /s, an expression for the magnetization is given, which supposes micro-domains reversal as a prevailing process. Finally, the general behavior of the relaxation time, depending on the magnetic field, is investigated. |
