Abstract

The critical temperature, Tc, for all presently known superconductors does not exceed 21'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 Tc for β€œordinary” superconductors would not exceed 20‐40oK is fairly well understood. At the same time, there apparently could exist high temperature superconductors for which Tc would reach liquid air temperature or even room temperatures. Possible means of producing high temperature superconductors are considered in this article which is based on the review published in Contemporary Physics, 9, 355 (1968), but includes also some new material. Special attention is paid to what can be called the exciton mechanism of superconductivity and its application to systems of the β€œsandwich” type and metallic conductors with layer structures.

Experimental and theoretical progress in high temperature superconductivity is reviewed. A consensus is emerging on many experimental facts but important aspects are still not known with certainty. Some theoretical progress has been made but at this time nobody knows what is causing T c to be as hig

We review some of the recent developments in our empirical understanding of the materials science of high T c materials. First, the distinguishing phenomenological Ginzburg-Landau features of these materials are identified, and the possible technological implications discussed. We then focus on two
