Improved alkali intercalation of carbonaceous materials in ammonia solution
B. G. Márkus, S. Kollarics, P. Szirmai +5
Alkali intercalated graphite compounds represent a compelling modification of carbon with significant application potential and various fundamentally important phases. We report on…
Possibility of an unconventional spin state of Ir in BaIrO single crystal
L. Yang, M. Jeong, A. Arakcheeva +11
We report the synthesis of single crystals of a novel layered iridate BaIrO, and present the crystallographic, transport and magnetic properties of this material.…
Charge carrier interaction with a purely electronic collective mode: Plasmarons and the infrared response of elemental bismuth
Riccardo Tediosi, N. P. Armitage, E. Giannini +1
We present a detailed optical study of single crystal bismuth using infrared reflectivity and ellipsometry. Colossal changes in the plasmon frequency are observed as a function of…
Persistence of molecular excitations in metallic fullerides and their role in a possible metal to insulator transition at high temperatures
V. Brouet, H. Alloul, S. Garaj +1
We present 13C NMR spin-lattice relaxation measurements (1/T1) in Na2CsC60 and Rb3C60 from 10 to 700K. The large temperature range of this measurement allow to define unambiguously…
Gaps and excitations in fullerides with partially filled bands : NMR study of Na2C60 and K4C60
V. Brouet, H. Alloul, S. Garaj +1
We present an NMR study of Na2C60 and K4C60, two compounds that are related by electron-hole symmetry in the C60 triply degenerate conduction band. In both systems, it is known tha…
Role of dynamic Jahn-Teller distortions in Na2C60 and Na2CsC60 studied by NMR
V. Brouet, H. Alloul, T. N. Le +2
Through 13C NMR spin lattice relaxation (T1) measurements in cubic Na2C60, we detect a gap in its electronic excitations, similar to that observed in tetragonal A4C60. This establi…
