Al substitution in MgB2 crystals: influence on superconducting and structural properties
J. Karpinski, N. D. Zhigadlo, G. Schuck +11
Single crystals of Mg1-xAlxB2 have been grown at a pressure of 30 kbar using the cubic anvil technique. Precipitation free crystals with x < 0.1 were obtained as a result of optimi…
Carbon substitution in MgB2 single crystals: structural and superconducting properties
S. M. Kazakov, R. Puzniak, K. Rogacki +6
Growth of carbon substituted magnesium diboride Mg(B1-xCx)2 single crystals with 0<x<0.15 is reported and the structural, transport, and magnetization data are presented. The super…
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…
