Andreev reflection in Bi_{1.8}Pb_{0.3}Sr_{1.9}Ca_2Cu_3O_x break junction [PDF]
The Physics of Metals and Metallography, 2006, Vol. 101, Suppl. 1,
pp. S27--S28., 2004 The current-voltage characteristic (CVC) of break junction made from polycrystalline Bi_{1.8}Pb_{0.3}Sr_{1.9}Ca_2Cu_3O_x is investigated. The experimental CVC has hysteretic feature that reflects a part of a curve with negative differential resistance.

Electronic Transport in a Topological Semimetal WTe2 Single Crystal [PDF]
Physics of Metals and Metallography 123 (2022) 1061-1067, 2023 Electrical resistivity, magnetoresistivity, and the Hall effect have been studied in a topological semimetal WTe2 single crystal in the temperature range from 12 to 200 K under magnetic fields up to 9 T. It has been found that quadratic temperature dependences of the electrical resistivity in the absence of a magnetic field and the conductivity in a ...

Negative Impurity Magnetic Susceptibility and Heat Capacity in a Kondo Model with Narrow Peaks in the Local Density of Electron States [PDF]
The Physics of Metals and Metallography, 2009, Vol. 108, No. 2,
pp. 107-115, 2009 Temperature dependencies of the impurity magnetic susceptibility, entropy, and heat capacity have been obtained by the method of numerical renormalization group and exact diagonalization for the Kondo model with peaks in the electron density of states near the Fermi energy (in particular, with logarithmic Van Hove singularities). It is shown that these
