Compressibility and thermal expansion of YBa2Cu3Ox
K. Grube, H. Leibrock, W. H. Fietz +6
The linear compressibilities and the thermal expansion of an untwinned, nearly optimal doped YBa2Cu3O6.94 single crystal were measured along the three crystallographic axes with a…

The Effects of Chemical Doping and Hydrostatic Pressure on Tc of Y(1-y)CayBa2Cu3Ox and NdBa2Cu3Ox Single Crystals
S. I. Schlachter, K. -P. Weiss, W. H. Fietz +7
We studied Tc of YBa2Cu3Ox (Y123), Y0.89Ca0.11Ba2Cu3Ox (YCa123) and NdBa2Cu3Ox (Nd123) single crystals with various oxygen contents x. Compared to Tc(x) of Y123 the Tc(x) curves of…

Structure and Tc of Y0.8Ca0.2Ba2Cu3O6.92 under High Pressure
Walter H. Fietz, Frank W. Hornung, Kai Grube +4
The lattice parameters and Tc of Y1-yCayBa2Cu3Ox have been determined under pressure up to 10 GPa using a diamond anvil cell. The results are used to test the extended charge trans…
