[Études par RMN des supraconducteurs pnictures à base de fer LaFeAs(O1 − xFx) et BaFe2(As1 − xPx)2]
Cet article de revue couvre nos résultats obtenus par RMN sur les supraconducteurs pnictures à base de fer et . Nous introduisons les mesures clefs qui ont sondé leurs propriétés tant normales que supraconductrices. La comparaison des deux systèmes montre que la structure du gap supraconducteur ainsi que la relation entre supraconductivité et fluctuations magnétiques, telles que vue par la RMN, sont très différentes dans les deux cas.
This review presents a summary of our NMR experiments on and . The authors introduce the key NMR experimental results which reveal their physical properties in the normal and superconducting states. From the comparison of the NMR results between the two systems, we point out that the superconducting gap structure and the relationship between superconductivity and magnetic fluctuations probed with NMR are quite different between the two systems.
