    Opis:
    This paper presents the experimental results of the magnetic and magnetoelastic investigation on the properties of $Fe_{70}Ni_8Si_{10}B_{12}$ amorphous alloy, subjected to thermo-magnetic treatment. Samples were annealed at temperature 350°C for 1 hour, in parallel magnetic field (4 kA/m), as well as in transverse field (350 kA/m). Sample annealed without magnetic field was also tested. Magnetoelastic tests were performed under uniform compressive stress, applied to the ring-shaped core, perpendicularly to the direction of magnetizing field. The results indicated that the thermo-magnetic heat treatment changes the magnetic characteristics, but does not have a significant influence on the coarse of magnetoelastic characteristics of $Fe_{70}Ni_8Si_{10}B_{12}$ amorphous alloy.

    Paper presents the results of investigations of the influence of the tensile stresses on magnetic characteristics of $Fe_{80}B_{11}Si_{9}$ amorphous alloy in as quenched and annealed state. For the tests, a special methodology of application of uniform tensile stresses to the ring shaped sample was developed. Due to special non-magnetic pads, the magnetizing and sensing coils can be wound around the core. Experimental results indicate high stress sensitivity of $Fe_{80}B_{11}Si_{9}$ alloy in both as-quenched and annealed state. Permeability of the core decreases over 64% and 58% for as-quenched and annealed core respectively, especially for lower values of the amplitude of magnetizing field.

    Opis:
    The paper presents a novel method of measurements of tensile stress dependence of the magnetic characteristics of ring-shaped cores made of soft amorphous alloys. In the presented method, the uniform tensile stress was applied perpendicularly to the magnetizing field direction. Magnetoelastic core with closed magnetic circuit was fixed on the non-magnetic backings enabling the conversion of compressive force into tensile stresses as well as it enables the core to be winded by magnetizing and sensing windings. Magnetoelastic characteristics measured under tensile stress, for $Fe_{25}Ni_{55}Si_{10}B_{10}$ alloy annealed in temperature 350°C for 1 h, are presented in this paper. The presented results indicate high tensile stress sensitivity of $Fe_{25}Ni_{55}Si_{10}B_{10}$ alloy. Moreover, together with magnetoelastic characteristics for compressive stresses (presented previously in the literature), the describes results create possibility of further development of models of the magnetoelastic effects in amorphous alloys.

    Paper presents the results of magnetoelastic tests of ring-shaped cores made of $Fe_{40}Ni_{38}Mo_{4}B_{18}$ amorphous alloy. The cores were subjected to thermomagnetic annealing under different values of magnetic field. The obtained results enabled us to connect the magnetoelastic characteristics of $Fe_{40}Ni_{38}Mo_{4}B_{18}$ amorphous alloy with the conditions of thermomagnetic treatment of the material.

    Opis:
    Information about magnetoelastic properties of newly developed amorphous magnetic alloys is very important from practical point of view, especially in the case of high permeability materials such as the Fe₆₁Co₁₉Si₅B₁₅ amorphous alloy. In the case of such materials, effect connected with the influence of external stresses on the magnetic properties of the alloy should be tested. This paper presents experimental results of the magnetoelastic properties investigation of the Fe₆₁Co₁₉Si₅B₁₅ amorphous alloy, annealed without magnetic field as well as in the magnetic field. Such thermo-magnetic treatment generated anisotropy has significant influence on the total free energy of magnetic material. In the magnetoelastic investigation, the compressive stress was applied to the ring shaped core, perpendicularly to the magnetizing field direction. Due to the fact, that cores with closed magnetic circuits were used, demagnetization did not change the balance of total free energy in the material.
