Sn. Gordeev et al., LARGE-SCALE CORRELATED VORTEX MOTION IN AN UNTWINNED YBA2CU3O7-DELTA SINGLE-CRYSTAL, Czechoslovak journal of Physics, 46, 1996, pp. 1729-1730
The vortex dynamics at temperatures below the vortex lattice melting t
ransition has been found to be highly dependent on the type of modulat
ion of the probing current. While in the case of de current the vortic
es now non-uniformly, the periodical ordering was observed for an asym
metrically square-wave modulated current.
