Opis:: The effect of thermal treatments (by the Joule heating and conventional annealing) on the coercivity and saturation magnetostriction constant in the amorphous and nanocrystalline Co$\text{}_{66}$Fe$\text{}_{4}$Mo$\text{}_{2}$Si$\text{}_{16}$B$\text{}_{12}$ alloy is reported. It is noticeable the near insensibility to the external stress of coercive field and anisotropy field (leading to extremely low value of magnetostriction 1.5×10$\text{}^{-8}$) achieved after the Joule heating by two steps (first one to relax the internal stresses and the second one to develop a fine nanocrystalline structure).

Opis:: We have studied the effect of annealing conditions on magnetic properties of amorphous CoFeNi-based glass-coated microwires. We show that annealing can be very effective for manipulation the magnetic properties of amorphous ferromagnetic glass-coated microwires. Low coercivity and high giant magnetoimpedance (GMI) effect have been observed in as-prepared Co-rich microwires. After annealing of Co-rich microwires we can observe transformation of inclined hysteresis loops into rectangular and coexistence of fast magnetization switching and GMI effect in the same sample. We demonstrate that the switching field value of microwires can be tailored by annealing in the range from 4 to 200 A/m.

Opis:: Amorphous ribbons of composition (Co$\text{}_{0.95}$Fe$\text{}_{0.05}$)$\text{}_{100-x}$Si$\text{}_{0.4x}$ B$\text{}_{0.6x}$, with x=25 and 30 were prepared by the melt-spinning technique. Current annealings at 600 mA were performed for annealing times between 15 s and 60 min. The magnetoimpedance response was investigated by submitting the ribbons to ac currents at frequencies in the 10-200 kHz range, with amplitudes between 1 and 15 mA (rms), and measuring their voltage response. The observed results show that a transverse anisotropy is induced by the thermal treatments, which can be evaluated by means of the magnetoimpedance effect. Due to its lower Curie temperature, the x=30 ribbons exhibited lower sensibility to the current annealings.
