Switching-field distribution in amorphous magnetic bistable microwires -: art. no. 024402

We present the temperature dependence of the switching field distribution of amorphous magnetic bistable microwires, which has unusual behavior in comparison with the experimental data presented up to now. The distribution is solved in terms of the thermoactivated model and its unusual temperature dependence is explained by the two contributions to the domain wall pinning in the amorphous microwires. The distribution width is found to be proportional to the switching field.
