La découverte de la supraconductivité à haute température dans les cuprates supraconducteurs en 1986 a révolutionné le secteur et remis en cause la théorie conventionnelle (BCS) de la supraconductivité. Malgré des avancées importantes dans la course aux plus hautes températures critiques, à ce jour, aucune théorie ne fournit une interprétation satisfaisante des propriétés de ces matériaux.L’évolution de la température critique en fonction du taux de strontium dans les solutions solides supraconductrices La2-xSrxCuO4 et La1,6 xNd0,4SrxCuO4 forme un dôme supraconducteur pour 0,05 0,11. En substituant une partie des ions lanthanes par des ions néodymes, la phase orthorhombique est stabilisée et la transition intervient quand x est proche de 0...
