Nearly zero-magnetostrictive amorphous wires do not present in the as-cast state the striking bistable magnetization process typical of high-magnetostrictive wires. Such a difference can be interpreted as a consequence of the low strength in the intrinsic magnetoelastic anisotropy. However if such an anisotropy is reinforced the magnetic behavior can be significantly changed. In the present work, the authors report for the first time the achievement of magnetic bistability in the as-cast state in a nearly zero magnetostrictive amorphous wire. The results show that a decrease of the measuring temperature below 250 K or the introduction of an additional magnetoelastic anisotropy, by means of the simultaneous application of tensile and torsional stresses, causes the appearance of a well defined single Barkhausen jump in the magnetization process.
