Analysis of the pseudogap-related structure in tunnel spectra of the superconducting Bi₂Sr₂CaCu₂O₈₊δ revealed by break-junction technique

Ekino, T.; Gabovich, A.M.; Voitenko, A.I. (Физика низких температур, 2008)

Tunnel conductance G(V)for break-junctions made of as-grown single-crystal Bi₂Sr₂CaCu₂O₈₊δ samples with Tc≈86-89 K was measured and clear-cut dip-hump structures (DHSs) were found in the range 80-120mV of the bias voltage ...
Anomalous temperature dependence of the stationary Josephson tunnel current in junctions between d-wave superconductors

Gabovich, A.M.; Voitenko, A.I. (Физика низких температур, 2014)

Stationary Josephson current Ic between d-wave superconductors was calculated for superconductor– insulator–superconductor structures with various rotations of crystals relatively to each other and the junction plane. The ...
Charge density waves in d-wave superconductors: thermodynamics and Josephson tunneling (Review Article)

Gabovich, A.M.; Voitenko, A.I. (Физика низких температур, 2013)

The problem of coexistence between charge-density-waves (CDWs) and superconductivity is revisited. Recent evidence was analyzed for different classes of materials with the emphasis on high-Tc oxides. For the latter, the ...

Gabovich, A.M.; Voitenko, A.I. (Физика низких температур, 2016)

Interaction energy between two point charges, WQQ′ , or two point dipoles, WPP′ , located in a medium with a constant dielectric permittivity near the plane surface of a metallic or semiconducting substrate with the spatial ...
Heat capacity of mesoscopically disordered superconductors: implications for MgB₂

Gabovich, A.M.; Voitenko, A.I.; Mai Suan Li; Szymczak, H. (Физика низких температур, 2002)

The electronic specific heat C as a function of temperature T is calculated for a mesoscopically disordered s-wave superconductor treated as a spatial ensemble of domains with continuously varying superconducting properties. ...
How does the break-junction quasiparticle tunnel conductance look like for d-wave superconductors?

Gabovich, A.M.; Voitenko, A.I. (Физика низких температур, 2017)

The bias-voltage, V, dependences of the differential tunnel conductance G(V) = dJ/DV were calculated for the quasiparticle current J flowing in the ab plane across the break junction made of d-wave superconductors. The ...
Paramagnetic effect of the magnetic field on superconductors with charge-density waves

Ekino, T.; Gabovich, A.M.; Voitenko, A.I. (Физика низких температур, 2005)

The limiting field Hp for spin-singlet superconductors with charge-density waves (CDWs), which paramagnetically destroys the ordered phase, possessing coexisting superconducting and CDW order parameters, is calculated ...
Power-law low-temperature asymptotics for spatially nonhomogeneous s-wave superconductors

Gabovich, A.M.; Voitenko, A.I. (Физика низких температур, 1999)

It is shown that low temperature asymptotics of various thermodynamic and transport properties of s-wave superconductors can become power-law ones if wide distributions of gap values exist, originating from structure ...
Spatial distribution of superconducting and charge-density-wave order parameters in cuprates and its influence on the quasiparticle tunnel current (Review Article)

Gabovich, A. M.; Voitenko, A.I. (Физика низких температур, 2016)

The state of the art concerning tunnel measurements of energy gaps in cuprate oxides has been analyzed. A detailed review of the relevant literature is made, and original results calculated for the quasiparticle tunnel ...
Spin-polarized electron tunneling between charge-density-wave metals

Ekino, T.; Gabovich, A.M.; Voitenko, A.I. (Физика низких температур, 2005)

For junctions between metals partially gapped by charge density waves (CDWs), the quasiparticle tunnel currents J(V) and conductances G(V) in external magnetic fields H are calculated as functions of H, the bias voltage ...

Dependences of the stationary Josephson current in symmetric and nonsymmetric tunnel junctions involving d-wave superconductors with charge density waves (CDWs) on the system parameters are calculated. Both the checkerboard ...
Superconductors with charge- and spin-density

Gabovich, A.M.; Voitenko, A.I. (Физика низких температур, 2000)

The properties of existing superconductors with electron spectrum instabilities, namely charge-density waves (CDW`s) and spin-density waves (SDW`s), are reviewed. In such substances the supercon-ducting gap exists over the ...
