Query: Measurement of Fluctuation-induced Diamagnetism in BSCCO-2212 single
  crystals using Magneto-optics   Fluctuation induced diamagnetism in BSCCO single crystals with different
doping levels (i.e., different oxygen stoichiometry) was measured using
magneto-optics (MO) in a wide frequency range up to several MHz. A shift in Tc
onset, measured by MO, of up to 6 K towards higher temperatures was observed at
high frequencies in those samples which are far from the optimally doped
condition. An explanation of the observed effect in terms of the phase
fluctuations of the superconducting order parameter is proposed.
