Magnetic hysteresis curves in YBa2Cu307 x single crystal are scaled by dividing the magnetic field H and the magnetisation M by the full penetration field H v and the associated magnetisation My. The scaling parameters, H v and Mv are determined experimentally as the merging point between the virgin

A resonance has been observed in the mixed state of YBaeCu30 7 thin films at h o) ~ 3 meV in the (hole) cyclotron resonance active mode of circular polarization. This chiral response is inconsistent with the conventional models of vortex dynamics. Based on a clean-limit theory recently developed by

We report the first real-time, direct magnetooptic images of the Meissner effect in doped YBa2Cu307\_-x single crystals. Measurements of flux profiles across field-cooled samples reveal increased pinning due to impurities. The strongest effect of the present dopants (Mn, Ca or Si) was found for Si.
