Dans cet article, on montre que l'isotope 43 du calcium est une bonne sonde RMN pour l'etude des proprietes des oxydes supraconducteurs a haute temperature. Dans l'etat normal, par la determination du deplacement de la raie, en fonction de la tempera

We have used $^{17}\mathrm{O}$ NMR to probe the magnetic homogeneity in both the paramagnetic and the ferromagnetic states of a high-quality ${\mathrm{Nd}}_{0.5}{\mathrm{Sr}}_{0.5}\mathrm{Mn}{\mathrm{O}}_{3}$ single crystal. The measured broadening o

In order to get some insight into the mechanism of the disproportionation of hydrogen peroxide catalyzed by calcium hydroxide, 43Ca NMR spectra of enriched samples of calcium peroxides and of their precursors have been studied in both solution and so

The inhomogeneous magnetic broadening of the 17 O and 207 Pb NMR spectra resulting from a distribution of the Knight shifts was studied in the metallic phase of BaPb 1− x Bi x O 3 oxides (0⩽ x ⩽0.33). It was shown that Bi atoms, which are rando

We report 17O NMR and SQUID measurements in two overdoped samples of the (Tl1−xPbx)Sr2CaCu2O7 family with Tc=65K (x=0.5) and Tc≊0K (x=0.2). The line shift 17K(T) has been measured for all three, well defined, 17O NMR lines and T1T has been studie
