Abstract
The preparation and characterization in structure and chemistry of the superconducting phases in Bi-Sr-Ca-Cu-O system are briefly summarized. The growth of the 85 K single crystal superconductor Bi2Sr2CaCu2Oy is outlined. The measurement of the anisotropic normal-state resistivities of the 85 K superconducting single crystal is presented in detail and the analysis of the incommensurate modulation in this compound is also given.

Résumé
On résume brièvement la préparation et la caractérisation, tant structurale que chimique, des phases supraconductrices du système Bi-Sr-Ca-Cu-O. La croissance d'un monocristal de Bi2Sr2CaCu2Oy supraconducteur à 85 K est particulièrement mise en évidence. On présente en ddtail les mesures de résistivité anisotrope dans l'état normal, et on analyse également la modulation incommensurable de ce composé.
