Mooij rule and weak localization
It has been shown that the observed correlation between the resistivity ρ of high-resistivity metallic alloys and the sign of the temperature derivative of their resistivity can be explained by taking into acc...

Suppression of 2D superconductivity by the magnetic field: Quantum corrections vs. The superconductor-insulator transition
Magnetotransport of superconducting Nd2−x CexCuO4+y (NdCeCuO) films is studied in the temperature interval 0.3–30 K. The microscopic theory of the quantum corrections to conductivity, both in the Cooper and in th...

Width of the zero-field superconducting resistive transition in the vicinity of the localization threshold
Resistive superconducting zero-field transition in amorphous In-O films in the states in the vicinity of the insulator-superconductor transition is analyzed in terms of two characteristic temperatures: the upper

Temperature dependence of the upper critical field as an indicator of boson effects in superconductivity in Nd2−x CexCuO4−y
The temperature dependence of the upper critical field B c 2 was determined from the shift of the resistive transition ΔT(B) in nearly optimally doped Nd2−x CexCuO4−y single c...

Observation of the parallel-magnetic-field-induced superconductor-insulator transition in thin amorphous InO films
We study the response of a thin superconducting amorphous InO film with variable oxygen content to a magnetic field. A field-induced superconductor-insulator transition (SIT) is observed that is very similar t...

Scaling analysis of the magnetic field-tuned quantum transition in superconducting amorphous In-O films
We studied the magnetic field-tuned superconductor-insulator transition (SIT) in amorphous In-O films with different oxygen contents and, hence, different electron densities. Whereas the two-dimensional scalin...

Resistive transition and upper critical field in underdoped YBa2Cu3O6+x single crystals
A superconducting transition in the temperature dependence of the ab-plane resistivity of underdoped YBa2Cu3O6+x crystals in the range T c≲30 K has been investigated. Unlike the case of samples with the optimal ...

Destruction of localized electron pairs above the magnetic-field-driven superconductor-insulator transition in amorphous In-O films
The field-induced superconductivity-destroying quantum transition in amorphous indium oxide films are investigated at low temperatures down to 30 mK. It is found that, on the high-field side of the transition,...

Low-temperature resistivity of YBa2Cu3O6+x single crystals in the normal state
A scan of the superconductor-nonsuperconductor transformation in single crystals of YBa2Cu3O6+x (x≈0.37) is done in two alternative ways, namely, by applying a magnetic field and by reducing the hole concentrati...

Transport properties of NdBa2Cu3O6+x ceramics at the edge of the superconducting region upon a decrease in carrier density as a result of oxygen disordering in the Cu-O x planes
An initially nonsuperconducting ceramic sample with the composition NdBa2Cu3O6+x is brought, by means of pressure and quenching, to a state with a high carrier density and a superconducting transition, after whi...

Pair tunneling in the low-temperature conductivity of the Cd-Sb alloy high-resistance state near the superconductor-insulator transition
We report a study of the temperature dependence, down to 30 mK, of the magnetoresistance of Cd-Sb alloy in the insulating phase obtained by annealing the quenched metallic superconducting ( T ...

Experimental study of resistivity of metallic materials with dynamic disorder
As a result of strong electron-phonon interaction, the enhancement of scattering with increasing temperature may decrease the mean free pathl in crystals down to interatomic distances:l≈a. This means that with re...

Resistivity of metallic systems with a strong dynamic disorder
If the static disorder in a system is increased the conductivity and the electron mean free path decreases to the limit where it reaches the Ioffe-Regal criterion. In this paper experimental results are presen...

Anisotropy of the electron-phonon scattering rate in metals
A method of measuring the temperature dependent part of the electron scattering ratev(T) for separate groups of electrons has been developed on the basis of the radio-frequency size effect. The temperature depend...

Temperature Dependence of the Electron Mean Free Path in Tin at Liquid-Helium Temperatures
To obtain detailed information on the electron mean free path in anisotropic metals, the elaboration of a method for investigating separate groups of electrons is needed. We made an attempt to use a previously...
