Magnetic viscosity in multilayers: a micromagnetic approach

We have simulated the relaxational behavior of Co/Ni multilayers with different layer thicknesses. The considered model is a 1D one where atomic planes are represented by single moments allowed to orient in 3D. The distribution of local easy axes mimic that present in polycrystalline materials. Our...

Summary:We have simulated the relaxational behavior of Co/Ni multilayers with different layer thicknesses. The considered model is a 1D one where atomic planes are represented by single moments allowed to orient in 3D. The distribution of local easy axes mimic that present in polycrystalline materials. Our results show that for small Ni layer thicknesses and large interlayer coupling the relaxation of the whole sample takes place in a single stage characterized by a waiting time, during which the film magnetization does not change, followed by a rapid reversal process. In the case of the films having larger Ni layer thickness and reduced interlayer coupling the relaxation proceeds through several stages.
