摘要：
We have studied the effect of thermal treatment on the sensitivity and stability of the switching field in bistable glass-coated Fe-Ni-Si-B microwire. We have found that annealing at 300 degrees C/1 hour leads to the increase in the sensitivity of the switching field to the applied external stress. Moreover, the switching field fluctuation decreases after such treatment as a result of domain structure stabilization through the structural relaxation.
