Dimensional Crossover of Vortex Dynamics Induced by Gd Substitution on Bi2212 Single Crystals

Z. W. Zhao, S. L. Li, H. H. Wen +1

The vortex dynamics of Bi${}_2$Sr${}_2$Ca${}_{1-x}$Gd${}_x$Cu${}_2$O${}_{8+\delta }$ single crystals is investigated by magnetic relaxation and hysteresis measurements. By substituting $Ca$ with $Gd…
