    Yanson, I.K.; Naidyuk, Yu.G. (Физика низких температур, 2004)
    Analysis of the point-contact spectroscopy (PCS) data on the new dramatic high-Tc superconductor magnesium diboride MgB₂ reveals quite different behavior of two disconnected σ and π electronic bands, deriving from their ...
  • Current-field diagram of magnetic states of a surface spin valve in a point contact with a single ferromagnetic film 
    Yanson, I.K.; Balkashin, O.P.; Fisun, V.V.; Yanson, Yu.I.; Naidyuk, Yu.G. (Физика низких температур, 2013)
    We present a study of the influence of an external magnetic field H and an electric current I on the spin-valve (SV) effect in point contact between a ferromagnetic thin film (F) and a sharp tip of a nonmagnetic metal ...
  • Investigation of the superconducting energy gap in the compound LuNi₂B₂C by the method of point contact spectroscopy: two-gap approximation

    It is shown that the two-gap approximation is applicable for describing the dV/dI(V) spectra of LuNi₂B₂C–Ag point contacts in a wide interval of temperatures. The values and the temperature dependences of the large and ...

    Naidyuk, Yu.G.; Nowack, A.; Ulbrich, E.; Freimuth, A.; Schlabitz, W.; Yanson, I.K.; Menovsky, A.A. (Физика низких температур, 1995)
    We have measured the dV/dI vs. V characteristics of point contacts between the heavy-fermion superconductor URu₂Si₂ and the conventional superconductors Zn and NbTi. Contacts between URu₂Si₂ and Zn behave like a ...
  • Observation of anisotropic effect of antiferromagnetic ordering on the superconducting gap in ErNi₂B₂C 
    Bobrov, N.L.; Chernobay, V.N.; Naidyuk, Yu.G.; Tyutrina, L.V.; Yanson, I.K.; Naugle, D.G.; Rathnayaka, K.D.D. (Физика низких температур, 2010)
    The point-contact spectra of the Andreev reflection dV / dI curves of the superconducting rare-earth nickel borocarbide ErNi₂B₂C (Tc≈11K) have been analyzed in the «one-gap» and «two-gap» approximations using the generalized ...
  • Point-contact-spectroscopy evidence of quasi-particle interactions in RNi₂B₂C(R=Ho, Y) 
    Jansen, A.G.M.; Wyder, P.; Yanson, I.K.; Fisun, V.V.; Canfield, P.C.; Cho, B.K.; Tomy, C.V.; McK. Paul, D. (Физика низких температур, 1997)
    The point-contact (PC) d²V/dI²-spectra of HoNi₂B₂C and YNi₂B₂C reveal structure at applied voltages corresponding to the phonon frequencies. At about 4 meV a maximum is observed in the phonon density of states by analogy ...
  • Point-contact-spectroscopy investigation of the Kondo size effect in CuCr and AuFe alloys 
    Fisun, V.V.; Yanson, I.K.; Mydosh, J.A.; van Ruitenbeek, J.M. (Физика низких температур, 2000)
    Size effects in Kondo scattering are studied on CuCr and AuFe alloys (TK=2 K and 0.2 K, respectively) by applying point-contact spectroscopy in break-junction type contacts. It is shown that as the contact diameter is ...
  • Point contact studies of the superconducting gap of CeRu₂ 
    Naidyuk, Yu.G.; Moskalenko, A.V.; Yanson, I.K.; Geibel, C. (Физика низких температур, 1998)
    The measured dV/dI(V) curves of point contacts between the intermetallic compound CeRu2 in the superconducting state and the normal metal Cu correspond fairly well to the Blonder-Tinkham -Klapwijk model. It is used to ...

    Balkashin, O.P.; Sukhodub, G.L.; Yanson, I.K.; Brill, T.M.; Jansen, A.G. M.; Wyder, P. (Физика низких температур, 2001)
    High-frequency point-contact (PC) spectroscopy is used to investigate the relaxation processes kinetics in the intermetallic rare-earth compound PrNi₅. A difference is observed in the spectral response between the conventional ...
  • Shell effects in alkali metal nanowires 
    Yanson, A.I.; Yanson, I.K.; Ruitenbeek, J.M. (Физика низких температур, 2001)
    After making a cold weld by pressing two clean metal surfaces together, and gradually separating the two pieces, a metallic nanowire is formed, which is progressively thinning down to a single atom before the contact ...
