Zhigadlo, N. D., Katrych, S., Bukowski, Z., Weyeneth, S., Puzniak, R., Karpinski, J.
Single crystals of SmFeAsO1-xFy of a size up to 120 micrometers have been grown from NaCl/KCl flux at a pressure of 30 kbar and temperature of 1350-1450 C using the cubic anvil high-pressure...
Low-temperature specific heat of the superconductor Mo3Sb7 (2008)
Tran, V. H., Miiller, W., Bukowski, Z.
The low-temperature specific heat of a superconductor Mo3Sb7 with T_c = 2.25 (0.05) K has been measured in magnetic fields up to 5 T. In the normal state, the electronic specific heat coefficient...
3D-xy critical properties of YBa2Cu4O8 and magnetic field induced 3D to 1D crossover (2008)
Weyeneth, S., Schneider, T., Bukowski, Z., Karpinski, J., Keller, H.
We present reversible magnetization data of a YBa2Cu4O8 single crystal and analyze the evidence for 3D-xy critical behavior and a magnetic field induced 3D to 1D crossover. Remarkable consistency...
Structural and Superconducting Properties of RbOs2O6 Single Crystals (2008)
Rogacki, K., Schuck, G., Bukowski, Z., Zhigadlo, N. D., Karpinski, J.
Single crystals of RbOs2O6 have been grown from Rb2O and Os in sealed quartz ampoules. The crystal structure has been identified at room temperature as cubic with the lattice constant a = 10.1242(12)...
Dubois, C., Santi, G., Cuttat, I., Berthod, C., Jenkins, N., Petrović, A. P., ...
We performed the first scanning tunneling spectroscopy measurements on the pyrochlore superconductor KOs2O6 (Tc = 9.6 K) in both zero magnetic field and the vortex state at several temperatures above...
