"Evidence for a temperature dependent anisotropy of the superconducting state parameters in underdoped SmBa2Cu3Ox";
Physical Review B, 82 (2010), 054510; 1 - 9.



English abstract:
The temperature dependence of the anisotropy of the superconducting state parameters, , was studied by
torque magnetometry for the high-temperature superconductor SmBa2Cu3Ox in magnetic fields of up to 9 T.
The measurements were performed on four underdoped single crystals with oxygen contents corresponding to
Tcs varying from 42.8 to 63.6 K. The anisotropy was found to be strongly temperature dependent while only
a weak dependence on the magnetic field was observed. No evidence for a field dependent superfluid density
was found. Possible origins of the temperature dependence of the anisotropy are discussed.
