Head Merisov B.; Khadzhaj G., Registration Date 19-02-2004 Organization Kharkov National University named after V.N.Karazin popup.description2 The Objects of studies are: the amorphous alloy Ti66Ni20Cu10Si4 and the icosahedral quasicrystals Тi45Zr38Ni17, as well as the platinum and system of the Josephson contacts. The Method of study is the measurement of electric resistivity. The Purpose of work: To get the information about the state of hydrogen in amorphous alloy Ti66Ni20Cu10Si4; to get the quantitative features of the process of hydrogen carrying in the icosahedral quasicrystals Тi45Zr38Ni17. By the way of experimental study of electric resistance of amorphous alloy Ti66Ni20Cu10Si4 (initial and saturated by hydrogen before concentration 6 аt.%) in the temperature interval 4,2-300 K and the aproximations of the temperature dependencies of resistivity by means of theories of scattering of electrons on phonons in amorphous alloys is shown that hydrogen forms the bonds with electron and therefore the radius of Fermi-sphere of the doped alloy is smaller than that in as-quenched alloys and the hydrogen exists there in "anion" state. The firststraightforward measurements of the diffusion of hydrogen in icosahedral quasicrystal Тi45Zr38Ni17 are done in the temperature interval 273-353 K. The temperature dependence of the diffusion coefficient obeys the Arrhenius's law with the activation energy 0.24 eВ. It is found the influence of the admixtures and structured defects on the Debye temperature and intensity of intra- and interband electron-phonon scattering, as well as electron-electron scattering in platinum. It is considered the conditions of synchronization of the Josephson contacts system by means of the resonance long line with open end.
