Mass enhancement, correlations, and strong coupling superconductivity in the beta-pyrochlore KOs2O6
M. Brühwiler, S. M. Kazakov, J. Karpinski +1
To assess electron correlation and electron-phonon coupling in the recently discovered beta-pyrochlores KOs2O6 and RbOs2O6, we have performed specific heat measurements in magnetic…
Large mass enhancement in RbOs2O6
M. Brühwiler, S. M. Kazakov, J. Karpinski +1
Heat capacity measurements on the recently discovered geometrically frustrated beta-pyrochlore superconductor RbOs2O6 (Tc=6.4 K) yield a Sommerfeld coefficient of 44 mJ/(molf.u. K^…
Intrinsic thermodynamic properties of the pyrochlore superconductor RbOs2O6 extracted by condensation energy analysis
M. Brühwiler, S. M. Kazakov, J. Karpinski +1
We develop a general procedure for the analysis of bulk thermodynamic data of a superconductor for samples containing a metallic non-superconducting second phase. The method is bas…
Superconductivity in Geometrically Frustrated Pyrochlore RbOs2O6
M. Brühwiler, S. M. Kazakov, N. D. Zhigadlo +2
We report the basic thermodynamic properties of the new geometrically frustrated beta-pyrochlore bulk superconductor RbOs2O6 with a critical temperature Tc = 6.4 K. Specific heat m…
Synthesis of superconducting pyrochlore RbOs2O6
S. M. Kazakov, N. D. Zhigadlo, M. Brühwiler +2
RbOs2O6, the third superconducting pyrochlore oxide (known so far), has been synthesized by encapsulation and by high pressure techniques. Suitable post chemical treatment of the a…
