    Notes: Abstract Effects of isothermal and isochronal annealing on the coercive field and the effective magnetic anisotropy in the as-quenched and the stress relieved amorphous alloy Co58Ni10Fe5Si11B16 were investigated. The mechanisms of the deterioration of soft magnetic properties in non-magnetostrictive amorphous alloys by annealing at low temperatures,T a 〈T c , are discussed. It turned out, that short-range ordering, i.e., topological short-range ordering (TSRO) and chemical short-range ordering (CSRO), caused by annealing lead to changes of the magnetostrictionλ s , and of the induced magnetic anisotropyK i . Both effects give rise to an increase of the coercive field. In addition, the kinetics of short-range ordering was studied and from these data, which are closely related to the stability of soft magnetic properties, the activation energy and a preexponential factor was derived:Q s.r=0.7eV,v 0=9.6×103s−1.

    The activation energy of crystallization of amorphous Fe40Ni40P14B6 (1982)

    Notes: Abstract The isothermal crystallization of Fe40Ni40P14B6 (Metglas 2826) has been studied by transmission electron microscopy, using static observations of partially crystallized ribbons at room temperature and in situ dynamic registration of the crystallization process at elevated temperatures. At all temperatures crystallization takes place by the nucleation and growth of individual crystals. Analysis of the transformation kinetics allowed to determine the nucleation rates and the activation energy for crystal growth. The growth velocity of the crystal phase was found to be controlled by the diffusion coefficient of phosphorus in this alloy withD 0=2.5×1010±1cm{swu2}/s andQ=(3.4±0.15)eV.

    Magnetic dipole fields at interstitial sites in disordered binary alloys of ferromagnetic crystals (1980)
    Springer

    Notes: Abstract The dipole fields at interstitial sites occupied by positive particles (μ +,p) in f.c.c. and b.c.c. diluted binary alloys of ferromagnetic metals are investigated. The characteristic shapes of the distribution functions of the dipole fields is shown to depend on the interstitial site occupied by the positive particle, and they may give information on the formation of diatomic complexes of the light interstitials with substitutional impurity atoms as well as on the degree of short-range order of the alloy.

    Critical current in YBCO thin film bridge studied using magneto-optic technique (1993)
    Springer
    Journal of superconductivity 6 (1993), S. 173-178

    ISSN: 1572-9605

    Notes: Abstract The magnetic flux distribution from a transport superconducting current flowing through an YBa2Cu3O7 (YBCO) thin film bridge is observed using a ferrimagnetic garnet indicator with in-plane magnetic anisotropy. After switching off the current from the maximum value that provides the electrically detected critical regime, the expected remanent flux was not observed. The only place where the irreversible magnetization takes place is a linear defect that crosses the bridge and thus reduces the electrically measured critical current compared with the value that could be reached without macroscopic defects. The observed reversibility of the main part of the sample is explained on the basis of theoretical calculations of the current-induced flux penetration: Perceptible penetration and trapping of the flux might be observed only upon the application of a current higher than approximately half the maximum critical current that could be reached in such a thin film without macroscopic inhomogeneities.
