Summary

THIS ARTICLE DEALS WITH THE DISCOVERY OF HIGH TEMPERATURE SUPERCONDUCTION AND REVIEWS THE SITUATION: DEFINITION OF THE MAIN MATERIALS (BLCO: 40 K, YBCO: 90 K, BSCCO: 110 K, TCBCO: 125 K) AND OF THEIR CHARACTERISTICS ; POSSIBLE APPLICATION FIELDS (ELECTRONICS WITH LOW LOSS LINES AT HYPERFREQUENCIES, SQUIDS AND JOSEPHSON DIODES -ELECTROTECHNIQUES) ; PROBLEMS WHICH ARE FACED (THIN LAYER METALLURGY -LIMITATION OF CURRENT DENSITIES -DISTINCTION BETWEEN THE PHYSICIST'S ROLE, WHO TRIES TO UNDERSTAND, AND THE CHEMIST'S, WHO TRIES TO DEVELOP NEW MATERIALS). PRESENTATION OF THE FIVE RESEARCH PROGRAMMES SELECTED FOR THE COMING YEARS. COLLABORATION BETWEEN THE DIFFERENT FRENCH RESEARCH CENTRES. MEANS INVOLVED. J. V.
