1303.6860 (I. Kokanović et al.)

Torque magnetometry of YBCO crystals above $T_c$    [PDF]

The magnetization of three small high-quality single crystals: YBa$_{2}$Cu$_{3}$O$_{7}$, YBa$_{2}$Cu$_{3}$O$_{6.5}$ and YBa$_{2}$Cu$_{3}$O$_{6.36}$ has been measured using torque magnetometry. Most of the data are consistent with the theory of Gaussian superconducting fluctuations, together with a strong cut-off above $T\gtrsim 1.1T_c$. The effect of inelastic scattering could be an important ingredient for achieving detailed understanding.
