Science, 1964
The number of superconductors known in 1935 was about 80, in 1950 over 100, and when last counted more than 900. Though the growth of a field cannot be measured by a single index, these numbers symbolize what has happened to the science of superconductivity; a sequence of discoveries has steadily enlarged the scope and importance of the subject.

Coexistence of ferromagnetism and superconductivity in a superconducting alloy
Physica, 1974Abstract A model for a superconducting alloy doped with magnetic impurities is solved exactly. The model consists of a combination of the BCS model and the Zener s-d exchange-interaction model. Its behaviour appears to be strongly dependent on the impurity concentration and the coupling parameters belonging to the BCS model and the s-d exchange ...

Superconductivity in the RExMo6S8
Solid State Communications, 1975The rare earth molybdenum sulfides RE x Mo6S8 (RE = rare earth) have been synthesized and are found to be superconducting with a few exceptions. This result, which is surprising in view of the high concentration of magnetic ions, is correlated with the particular structure of these compounds based on on units of Mo6S8.

Superconductivity and Ferromagnetism
IBM Journal of Research and Development, 1962Superconductivity and ferromagnetism were considered exclusive phenomena for many decades. Ever since Kamerlingh Onnes' discovery that strong magnetic fields will destroy superconductivity it had been assumed that the large internal, or Weiss field, in a ferromagnet would never permit the occurrence of superconductivity.

Superconductivity and superconducting Materials
Canadian Metallurgical Quarterly, 1972AbstractOur present understanding of the properties of high-field superconductors, specifically critical temperature, critical field and critical current, is reviewed. The processing of commercial materials is described, and present and future applications are discussed. Resume L'auteur passe en revue les connaissances actuelles des supra-conducteurs a

Science, 1968
Phosphorus, the element itself, becomes superconducting near 4.7°K and at pressures exceeding 100 kilobars. This constitutes one of the four last missing links in the proof that superconductivity is normal behavior for every truly metallic sp element. The three remaining ones are arsenic, sulfur, and iodine.

Superconductivity and Hype-Superconductivity
Physics Bulletin, 1987There's never been quite the media coverage for solid state physics that we have experienced over the past year. Of course, there is something magical about superconductivity – perpetual motion at least, if not the promise of free electricity as suggested by some of the headlines.

Superconductivity and Superconducting Fluctuations
1977The first part of this paper will be devoted to an outline of the theory of superconductivity in order to develop sufficient background to appreciate what effects fluctuations have upon super-conductivity. The second part by Dr. H. Gutfreund will discuss in more detail superconductivity and the more general problem of instabilities of one-dimension ...

Superconductivity and Superconductive Electronics
1990Abstract : The Stanford Center for Research on Superconductivity and Superconductive Electronics is currently focused on developing techniques for producing increasingly improved films and multilayers of the high-temperature superconductors, studying their physical properties and using these films and multilayers in device physics studies.

Metals formed from light elements are predicted to exhibit intriguing states of electronic order. Of these materials, those containing boron are of considerable current interest because of their relatively high superconducting temperatures. We have investigated elemental boron to very high pressure using diamond anvil cell electrical conductivity ...
