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
Tc´s 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.
