TL;DR: In this paper, the exciton mechanism of superconductivity has been investigated for the production of high temperature superconductors, for which the critical temperature T c would reach hundreds of degrees, or at least liquid air temperature.
Abstract: The critical temperature, T c, for all presently known superconductors does not exceed 20°K. This fact obviously limits the range of applications of superconductivity in technology in a very fundamental way. On the whole, the reason why the value of T c for ‘ordinary’ superconductors should not exceed 20–40 °K is fairly well understood on the basis of the existing theory of superconductivity. At the same time, there apparently could exist high temperature superconductors for which the temperature T c would reach hundreds of degrees, or at least liquid air temperature. Possible means of producing high temperature superconductors are considered in this article. Special attention is paid to what can be called the exciton mechanism of superconductivity.

TL;DR: In this article, the existence of long-range order of both kinds in the same material was finally established recently with the advent of the families of ternary compounds which have come to be known as magnetic superconductors.

TL;DR: In this article, the authors summarize the literature on high temperature superconductivity in light of a dynamic dielectric formalism and show that with a suitable choice of parameters high Tc superconductivities can occur.
Abstract: We summarize the literature on high temperature superconductivity in light of a dynamic dielectric formalism. It is shown that with the appropriate choice of dielectric function e(ω, q) one can describe superconductors and with a suitable choice of parameters high Tc superconductivity can occur. It is shown that the parameters for certain systems in particular for CuCl are consistent with the occurrence of a hgh Tc superconductivity state.
