Localized versus itinerant magnetic moments in Na0.72CoO2
J. L. Gavilano, B. Pedrini, K. Magishi +5
Based on experimental 59Co-NMR data in the temperature range between 0.1 and 300 K, we address the problem of the character of the Co 3d-electron based magnetism in Na0.7CoO2. Temp…
Magnetic Phase Transition at 88 K in Na0.5CoO2 revealed by 23Na-NMR investigations
B. Pedrini, J. L. Gavilano, S. Weyeneth +6
Na0.5CoO2 exhibits a metal-insulator transition at 53 K upon cooling. The nature of another transition at 88 K has not been fully clarified yet. We report the results of measuremen…
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…
Unconventional Charge Ordering in Na0.70CoO2 below 300 K
J. L. Gavilano, D. Rau, B. Pedrini +4
We present the results of measurements of the dc-magnetic susceptibility chi(T) and the 23Na-NMR response of Na_{0.70}CoO_{2} at temperatures between 50 and 340 K. The chi(T) data…
Specific heat of MgB_2 after irradiation
Yuxing Wang, Frederic Bouquet, Ilya Sheikin +6
We studied the effect of disorder on the superconducting properties of polycrystalline MgB_2 by specific-heat measurements. In the pristine state, these measurements give a bulk co…
