In this work we studied influence of time and temperature of stress annealing on magnetic properties of amorphous Co-based and CoFeNi-based microwires. We showed that this type of treatment can be very effective for manipulation of magnetic properties of amorphous ferromagnetic glass-coated microwires. Co-based microwires keep S-shape hysteresis loop after any annealing. Annealing of Co-based microwires at different conditions allows tailoring of the saturation field. CoFeNi-based microwires present either S-shape or rectangular shape of the hysteresis loops depending on the value of the axial stress during the annealing. We demonstrated the possibility to change the switching field of microwires with acquired bistability in the range from 0.5 to 25 A/m.
