Evidence for s-wave superconductivity in the new beta-pyrochlore oxide RbOs2O6

K. Magishi, J. L. Gavilano, B. Pedrini +5

We report the results of 87Rb NMR measurements on RbOs2O6, a new member of the family of the superconducting pyrochlore-type oxides with a critical temperature Tc = 6.4 K. In the n…
