Scaling of the Equilibrium Magnetization in the Mixed State of Type-II Superconductors
I. L. Landau, H. R. Ott
We discuss the analysis of mixed-state magnetization data of type-II superconductors using a recently developed scaling procedure. It is based on the fact that, if the Ginzburg-Lan…
Study of pressure effect on the magnetic penetration depth in MgB
D. Di Castro, R. Khasanov, C. Grimaldi +3
A study of the pressure effect on the magnetic penetration depth in polycrystalline MgB was performed by measuring the temperature dependence of the magnetization under a…
Study of the magnetic penetration depth in RbOs_2O_6
R. Khasanov, D. G. Eshchenko, D. Di Castro +8
Measurements of the magnetic field penetration depth λin the pyrochlore superconductor RbOs_2O_6 (T_c\simeq6.3 K) were carried out by means of the muon-spin-rotation (\muSR) techni…
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…
Evidence for Single-gap Superconductivity in Mg(B_{1-x}C_x)_2 Single Crystals with x=0.132 from Point-Contact Spectroscopy
R. S. Gonnelli, D. Daghero, A. Calzolari +6
We report the results of the first directional point-contact measurements in Mg(B_{1-x}C_{x})_2 single crystals with 0.047 <= x <= 0.132. The two-gap superconductivity typical of M…
On the interpretation of the equilibrium magnetization in the mixed state of high-Tc superconductors
I. L. Landau, H. R. Ott
We apply a recently developed scaling procedure to the analysis of equilibrium magnetization M(H) data that were obtained for T-2212 and Bi-2212single crystals and were reported in…
Pressure effect on the in-plane magnetic penetration depth in YBa_2Cu_4O_8
R. Khasanov, J. Karpinski, H. Keller
We report a study of the pressure effect (PE) on the in-plane magnetic field penetration depth lambda_{ab} in YBa_2Cu_4O_8 by means of Meissner fraction measurements. A pronounced…
Anisotropy and internal field distribution of MgB2 in the mixed state at low temperatures
M. Angst, D. Di Castro, D. G. Eshchenko +11
Magnetization and muon spin relaxation on MgB2 were measured as a function of field at 2 K. Both indicate an inverse-squared penetration depth strongly decreasing with increasing f…
Damping of the de Haas-van Alphen oscillations in the superconducting state of MgB_2
J. D. Fletcher, A. Carrington, S. M. Kazakov +1
The de Haas-van Alphen (dHvA) signal arising from orbits on the Fermi surface sheet of the two-gap superconductor MgB has been observed in the vortex state below .…
Pressure effects on the transition temperature and the magnetic field penetration depth in the pyrochlore superconductor RbOs_2O_6
R. Khasanov, D. G. Eshchenko, J. Karpinski +5
We report magnetization measurements under high hydrostatic pressure in the newly discovered pyrochlore superconductor RbOs_2O_6 (T_c\simeq6.3K at p=0). A pronounced and {\it posit…
Equilibrium magnetization in the vicinity of the first order phase transition in the mixed state of high-Tc superconductors
I. L. Landau, H. R. Ott
We present the results of a scaling analysis of isothermal magnetization M(H) curves measured in the mixed state of high-Tc superconductors in the vicinity of the established first…

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…
Finite-size and pressure effects in YBa_2Cu_4O_8 probed by magnetic field penetration depth measurements
R. Khasanov, T. Schneider, J. Karpinski +1
We explore the combined pressure and finite-size effects on the in-plane penetration depth λ_{ab} in YBa_2Cu_4O_8. Even though this cuprate is stoichiometric the finite-size scalin…
