Description

It has been shown by Kang et al. that the modulation of BiSrCaCuO (2212) compounds along the b axis can be of 3 different kinds: M1, M2, M3. This modulation can be related to the preparation conditions and to the Tc value of the superconductor. It is shown here that M1 and M3 can occur in the same crystal in the case of quenched samples, which corresponds to the stacking of different layers modulated as M1 and M3. The two different modulations may occur either along the same direction, or in two perpendicular directions

Abstract (French)

Kang et al. ont montre que la modulation de BiSrCaCuO (2212) le long de l'axe b peut etre de 3 sortes: M1, M2, M3. Cette modulation peut etre reliee aux conditions de preparation et a la valeur de Tc du supraconducteur. On montre ici que M1 et M3 peuvent coexister dans un meme cristal dans le cas d'echantillons trempes, ce qui correspond a l'empilement de differentes couches modulees suivant les types M1 et M3. Ces deux modulations differentes peuvent se produire soit suivant la meme direction, soit suivant deux directions perpendiculaires
