En effet, dans le cas plus simple de chaînes ou d'échelles de spin isolantes, ces impuretés induisent dans leur voisinage immédiat un magnétisme alterné révélateur des corrélations électroniques. Pour mesurer ces corrélations et ainsi déterminer leur lien éventuel avec la supraconductivité, nous proposons d'étudier l'effet de défauts ponctuels tels que des impuretés non magnétiques. Dans ces systèmes, le plus souvent des oxydes de métaux de transition, les fortes corrélations entre électrons affectent profondément leurs propriétés électroniques et induisent de nouveaux états originaux : liquides de spins, supraconductivité, etc. La découverte des supraconducteurs à haute température critique a ouvert la voie à une nouvelle physique, celle des fermions fortement corrélés.

These observations allow to get a better understanding of both normal and superconducting state of these oxides, both full of surprises. 236–240.Discovery of high $T_$ superconductors, using local probes such as nuclear magnetic resonance. Böer, Survey of Semiconductor Physics (Van Nostrand Reinhold, New York, 1990), pp. A more complete treatment would use the appropriate value of α each photon energy. In order to obtain an initial estimate of the impact of excitons, α = 0 was used in these equations since α<,0.1 cm −1 for the energy range considered. 66, 174 (1995) show that band-to-band absorption coefficient and internal quantum efficiency (IQE) are proportional for weak absorption and that spectral response is proportional to IQE if only a narrow spectral range is considered and the surface reflectance varies negligibly over that range. If b is in the expected range we expect no structure in addition to that discussed in the earlier work. The spectral regions where G x /G total is high are among those where the thresholds of excitonic absorption create “humps” in the absorption spectrum (see Ref.
