Opis:: In this contribution a less common experimental procedure is presented, which includes simultaneous application of electrical pulse heating, and longitudinal mechanical stress, applied along the ribbon length, for the magnetic property tailoring. The annealing is performed in protecting atmosphere in a vertical tube furnace by applying a weight at the free, cold bottom end of the ribbon. In these circumstances neither nanometer-size grains nor the concentration-distribution have been developed. The static coercive force, anisotropy and demagnetizing factor are monitored as a function of pulse number.

Opis:: The effects on the evolution of coercivity (H_c) and brittleness in FINEMET-type precursor glasses during traditional (isothermal) and pulse heat treatments are compared. The time and temperature dependences of these quantities are monitored during the series of isothermal and pulse heat treatments. The activation energy for H_c relaxation is lower than that for the brittleness evolution, however, dramatic changes in the values of these quantities can be detected above 300°C. Both quantities change mainly with temperature, they are less time-dependent.

Opis:: In Fe based glasses not solely the stress-sensitive magnetic properties, but also the amorphous Curie temperature $(T_C^{am})$ can be altered by hydrogen absorption or due to the low temperature "heat treatments" in liquid $N_2$ (-196°C). The sign and magnitude of this $T_C^{am}$ shift is strongly compositional dependent, but it is also influenced by the thermal history of glasses (heat treatments). In this paper new experimental results are presented, which were obtained on FeCrB alloys, supporting the previous observations. An attempt of interpretation of the results is also made, which is based on the existence of the quenched-in phase reminiscences, being inherited from the liquid structure.
