Very high applied pressure induces superconductivity with the transition temperature (T c)
exceeding 19 K in elemental yttrium, but relatively little is known about the nature of that …

Sorption of yttrium on nano-thorium oxide and zirconium oxide was carried out as a function
of pH, contact time, concentration, temperature and co-ions. The effect of initial yttrium ion …

The dependence of the critical temperature $ T_c $ of high-temperature superconductors of
various families on their composition and structure is proposed. A clear dependence of the …

The ab initio calculations suggest (Y. Ma et al.), that the high-pressure (p= 200 GPa)
superconducting state in BiH 5 and BiH 6 compounds characterizes with a high value of the …

In the 1950s, starting from the general theory of phase transitions of the second kind,
Ginzburg and Landau presented a theory describing the properties of superconductors. To …

The properties of the superconducting state in the amorphous Sn1− x Cu x thin films were
characterized. The concentration of copper changes in the range from 0.08 to 0.41. The …

The dependence of the critical temperature of high temperature superconductors of various
families on their composition and structure is proposed. A clear dependence of the critical …

In the present paper, we report a theoretical study of the magnetic London penetration depth
in ultrathin Pb films consisting of five to ten monolayers. Our calculations were performed …

The thermodynamic properties of the superconducting state in the amorphous ${\rm Sn_ {1-
x} Cu_ {x}} $ thin films have been characterized. The concentration of copper changes in the …
