- Abstract
The influence of a magnetic field on the shape of the superconducting transition
is dramatically different in high temperature superconductors as compared to
conventional superconductors. A consistent description of these unconventional
phenomena is crucial for the design of practical applications of the cuprate
superconductors. We report measurements of the superconducting transition in
c-axis oriented TmBa2Cu3O7-δ and TmBaSrCu3O7-δ thin films In magnetlc fields
up to 13 T, applied in the transverse (B||c) and longitudinal (B˪c) directions. The
upper part of the transition is dominated by critical order parameter fluctuations
and the characteristic "fan-shape" of the resistivity curves can be quantitatively
described by a recent anisotropic renormalized fluctuation theory.- Organisation(s)
